I am a Brazilian Jiu-Jitsu student and I bought a 0.5 inch band for my fingers and toes. The band is quite stretchy and doesn't hold up very well once you start sweating. It sticks to itself pretty well, but if one of the ends gets tangled, the glue will essentially fry. If you grip your partner's gi enough, it will start to loosen after about half an hour of hard training. soft grip (because it's stretchy) and the volume of the case make it a good deal, but I won't be ordering it again.
