We make cuffs and collars you’ll totally forget about.
Our Biothane® cuffs and collars are lightweight, secure and above all else, comfortable. The most common comment we get from owners is that they forget they’re wearing them throughout the day until they get home, or when a partner tugs them. Made from ultra-comfortable Biothane® strapping, smooth and glossy ABS latches and stainless metal components, our restraints are a perfect addition to your playtime get-up, and are more than tough enough to join your daily attire too.
We’ve developed cuffs and collars that use 3D-printed latches that integrate sturdy D-rings to keep you or your submissive a moment away from easy restraint, and have made them so low-profile that they easily hide under your clothing when necessary. Not that you’d know they’re 3D-printed at first glance; we’ve worked hard to perfect a vapour smoothing process that dissolves layer lines and raises a beautiful gloss finish, all while making the parts easy to clean and extremely strong for their size.
Our cuffs and collars use a simple, unbroken Biothane® band that’s held semi-permanently into these latches on one end, and on the other slides in to complete the restraint, securing simply with our low-profile security screws. You can upgrade all our restraints to be permanently attached too, for those with kinks for the long term like us.

What makes our restraints so nice?
Beautiful Biothane® straps for comfort, hygiene and strength
Biothane® is an incredible alternative to leather, but isn’t anything like the cheap, flaky pleather you might have experienced with other restraints. This material is used extensively in equestrian and high-end dog products, and is extremely strong, impervious to odour and fully waterproof. It doesn’t degrade like other leather alternatives over time either, and won’t turn turn flaky, sticky or frayed. It comes in a huge range of colours, from strong plain shades, to bright neons and delicate pastels, to options with retro-reflective stripes (for your safety!) and fully-printed designs.
Integrated D-rings for easy restraint, in a variety of styles
With our new designs, all cuffs and collars come with D-rings by default, and they’re a built-in part to the restraints, meaning they allow for snugger fits and better comfort. Our included D-rings are made of beautiful, long-lasting 304 stainless steel, welded and unbroken for ultimate strength, 3mm thick. For those with a love for thicker hardware (guilty!), we also offer a selection of D-rings that are 4.5mm thick, and for those with other preferences, nylon plastic and D-ring-free options.
When we’re making your cuff clasps, we 3D print them out of strong ABS plastic, so how do the D-rings get in there? Well, we pause our printers briefly at the perfect height to snap in each D-ring, which is then enclosed by the printer as an integral part of the cuff. There’s no seams, no fasteners and no weak points keeping the D-rings in place, just an unbroken glossy surface. Very nice.
Endless customisation with colour options and vinyl lettering
Whether you’d like a subtle black-on-black design or go full fluorescent neon, our restraints have you covered. In addition to our wide range of colours and styles for the main bands, we’ll also happily make your plastic parts in any colour we can get our hands on. Plus, if you’d like an extra-personal touch, we can add your pet name, identity or whatever you fancy on fancy vinyl to the restraints you wish. We can add anything from subtle gloss black lettering on your black cuffs to holographic dazzle patterns on your safety-jacket yellow collar. We’ve done many ambitious designs so far, so as long as our machines can make yours, we’ll make it happen!
Faceplates for every occasion
If you’re showing off your cuffs at a play party, convention or somewhere else you’d like to add an extra pop of your personality, we make beautiful shiny faceplates for all our cuffs and collars! Made with the same process as our main restraint parts, they snap over your D-rings to cover the main lock body. We don’t design these for 24/7 use, unlike our restraints themselves, but they’re a perfect show-piece. Available in several designs (plus, we’re working on others), we’re also happy to make your own personal icon, symbol or number part of your own set!
If you don’t want D-rings on your cuffs or collar? Not to worry, we’ll provide you with faceplates that snap over the lock itself!
Some of our colours are available with authentic 3M retro-reflective stripes, for those who like the safety aesthetic.
We offer a range of D-rings, from our included 3mm thick stainless steel to chunky 4.5mm thick options in rainbow, black and golden colours.
Heat-applied vinyl lettering adds an inexpensive but deeply personal touch to almost all of our Biothane® styles.

Got a question?
We get plenty of questions about our restraints – here’s the most common!
How do you make your restraints?
We design and manufacture all our restraints completely in-house in the UK using only skilled lesbian labour. When we get your order for cuffs, for example, we check your specifications and measurements, and reach out to confirm them if needs be.
Then, we start by printing your plastic parts, using our own from-scratch designs, using high quality ABS plastics. If your order asks for D-rings (they’re free!), we pause the print to completely lock them inside your restraint clasps. Then, once the printer finishes its magic, we clean up anything we need to, including the bottom surfaces and any small burrs, and thoroughly clean and degrease the parts and let them dry. When ready, we then suit up in protective gear, turn on our ventilation and fire suppression system and expose your parts to multiple courses of boiling acetone vapours, which gradually smooths the outside edges and seals the parts inside and out, and leave them to fully cure for up to several days. This leaves beautifully smooth, comfortable and easy-to-clean parts that are ready for years of wear and tear. If you’ve tried wearing 3D printed restraints before, you may have been put off by scratchy layer lines that trap sweat and dirt, or by the overall rough appearance. You will not be put off by anything like that with these parts!
While we process our parts by hand and small variations and imperfections are inevitable, this chemical treatment process leaves truly smooth to the touch, burr-free and sealed components, meaning you can wear them indefinitely. Our plastics are body-safe and suitable for anything your skin might regularly be exposed to (be careful with nail varnish remover, though!).
Your cuffs and collars will consist of our main clasp housings plus some additional locking parts and the parts for your security bit key. Once they’re ready, we cut your Biothane® straps to size, taking your measurements and adding the necessary length to be comfortable with our low-profile system, then punch one hole in each end, seal the ends with leather sealant, and add rustproof grommets for strength. Then we do a quality check, fit check and package them up to be sent off to you!
Can you make mine like…?
If at all possible, yes! Whether you have a burning desire for a custom coloured clasp to match your fursona or your existing kink gear or you’d like your submissive’s cuffs to reflect how locked they are, we can customise your order to almost any request. If you’d like custom plastics colours, just let us know during your order! If you’d like cut vinyl designs to be added to the restraints, simply add on the option before you check out.
If you’d like some extra special D-rings in exotic colours or materials, or other metal hardware, we’ll be happy to source parts that work. For strap colours, we’ll do our best to match what colours of Biothane® we can get our hands on, and for locking clasp and other plastic colours, if we can source it in a safe ABS, we’ll get it for you. Custom materials and colours may have a small surcharge for us to obtain them, but we’ll let you know in advance!
How low profile and light are they?
We cut our restraint bands to whatever size you ask for, plus a few millimetres for them to sit comfortably with our low-profile locking system, so the full dimensions and weight depend heavily on your measurements. Our clasps assemblies are the other main component in your restraints, and the main dimensions are listed below.
| Dimension | 19mm cuffs/collars | 25mm collars | |
|---|---|---|---|
| A | Clasp width | 25mm | 31mm |
| B | Clasp height | 25mm | 31mm |
| C | Clasp main thickness | 12mm | 12mm |
| D | Clasp max thickness over D-ring | 17mm | 19mm |
If you opt for chunkier 4.5mm thick D-rings, D increases by 1mm. If you opt for no D-rings, D is equal to C.
Our cuffs are incredibly light for their strength, and a typical full set of 4 cuffs and collar, including stainless steel D-rings, often weighs only 140-190g (5-6.5 oz)! Including stainless steel D-rings, each 19mm cuff/collar clasp weighs around 8g (0.3 oz) and 25mm collar clasps weigh around 9.5g (also 0.3 oz). Other D-rings affect overall weight slightly.
The clasp is rounded for comfort, and the rest of the cuff is highly flexible, leading to an extremely easy to wear restraint.
Is there an option for no metal whatsoever?
For those of you who work or frequently visit workplaces, airports and other areas with metal detectors, we have options for you! If you select either nylon plastic D-rings or no D-rings whatsoever on your restraints, the only metal pieces will be the screw-lock mechanism itself and the small grommets on each end of the main Biothane® bands. Overall, it’s about the same amount of metal as a small piece of jewellery and in our experiences is unlikely to trigger metal detectors. For those who have successfully worn plastic chastity devices with small metal locks through airport security, it’s a little less metal than that – less than 1.6g (0.056 oz)! If you work in an MRI lab or something and want no metal whatsoever, you can upgrade your restraints with our permanent pin kit, but keep in mind that once they go on, they won’t come off easily!
How do I measure for my restraints?
