I'm looking for a corner rounder punch that is strong enough to also round corners of a business card (or medicare card) laminated in plastic (one card at a time is fine). I have a 1/4" radius punch that is strong enough to do the job but makes corners that are too large for business cards size, 1/4" radius. For this size, a 1/8" (3 mm) radius round is more appropriate. I can't find one for less than $50. Anyone know of something that would do the job for me?
Thanks in advance.
