Not a perfect holder for these, but will do in a pinch! Tried to router out about a 1/16" recess, but failed...might try again. Downside to this, with no recess, it's just card against plastic, so potential for scratches are greatly increased! With the cards sandwiched in, it makes it just a bit too thick for the holder, so had to dremmel out the channel just a bit (if i get the recess right, this shouldn't have to happen)....it's a 4x9 business license holder off the jungle site....would mind seeing other ideas if anybody has them!
