Atoma: A Rollabind alternative?
I popped in a college bookstore near my house and found disc-bound index and fobster size card sets from Atoma, which is a Netherlands-based company. Their website is at www.atoma.be and their US-based distributor is Myndology at www.myndology.com. The 3x5 cards were $3.59 and the fobster size cards were $2.59. I did not see any kind of punch. They seem to want to sell refill cards. I think the Rollabind punch will work.
