Please contact me if you are interested in a custom order. The time to finish orders may vary from a few days to a week depending on the time of year. Also if I order fabric from Spoonflower (take a look at them! They have beautiful patterns you can't find anywhere else and a bunch of original fan-created patterns for just about anything you can get excited about!) it will take an extra 8-10 days for the fabric to get to me. Custom wrist cuffs start at $38 and ankle cuffs start at $43. Cuffs using special materials or designs may be priced higher. Larger and smaller sizes get charged the same custom price because people of every size deserve equal access to nubby softness.

The nylon strap is heavy-duty strap used for making dog leashes. It is rather stiff, and has a slight shine to it. The nylon holds its shape better, but doesn't conform to the wearer's shape as much so they may feel more stiff.

The polyurethane strap is softer, more like the kind of strap you might see on a light backpack. Polyurethane is softer and conforms more to the wearer's shape, but the strap has a tendency to wrinkle a little around the rings. I've still not had any problem with durability, but some people may be bothered by the appearance.

Both are durable and I have not experienced breakage with either. Keep in mind that available colors differ by material.
