Just FYI on this thread - if you have Vibram from 3 or more years ago it's straight gold on the Facebook collector pages. I'm talking $25-100+ depending on mold/color patterns. If you're real curious post up pics and I can point you in the right direction.
For real? I couldnt give away any vibram discs back in the day. I used all mine I acquired for water discs. Oh well.
