This kit is great for bedroom bondage and travel since it's light and space efficient. The cuffs are made of heavy-duty neoprene and reinforced with nylon for extra security. Each restraint has a Velcro closure for fast security. Our popular beginner's Bondage Kit is packed with the essentials at a good price. It was a bit disappointing to find only two tethers in the box however it is sufficient enough for basic restraining. The cuffs are fairly durable, I haven't been able to pull them apart yet and they are much more comfortable than handcuffs. Although this set on its own has limited use, with a bit of creativity it can be combined with other sets and equipment rather nicely. For example rope can substitute the lacking 2 tethers for a four-point spread or a tether can be used with the Under the Bed Restraint system to add a fifth attachment for a collar. The cuffs will break without much strength from the sub. I'm in the process of replacing my old bondage gear and this set is a good value. The cuffs are easy to use and won't open simply by pulling on them thanks to the double Velcro design(one strap sets the size, the other strap keeps the first in place. The tethers are nice and strong, I haven't tested the strength of the adjustable portion of the tethers yet but they look sturdy enough. The blind fold is about a centimeter too narrow over the eyes, someone can still see under the blindfold, however this can be cleared up with some bondage tape or breaking them in enough to lay flat over the eyes. With a little practice all the minor inconveniences work out. All models appearing on the website were at least 18 years of age on the date of principal photography. Bondage Kit
