Rubber band money clip

Recently a friend of mine, dropped and broke his money clip. His quick solution was to use a rubber band. He noted how much better he liked it, because it was so light! And money clips which are usually made in sterling silver are very heavy. However, one problem that came up was that the rubber bands would break easily. I suggested using one of my hair ties, but with hair ties you can't wrap them around more than twice and the money falls out.

I then looked online and there were only a couple solutions: One, an elastic money clip, but they are rare and rather boring looking. Two, a titanium money clip, which looks like a silver one, except its extremely light weight.

This is one design problem where I think there are numerous solutions to be discovered!
