“Mister B carries this good quality and quite affordable sturdy slave collar, made of biothane. Biothane is a fortified silicone like material. Since it’s a non-porous material, this slave collar is excellent for wet or dirty games since the biothane won’t be affected or become smelly.Lockable too.Provided complete with leash, which we consider as a nice detail.Strong enough for hard bondage play, unsuitable for suspension purposes.Also available in the same style / material: ankle and wrist restraints.”
