These laminating pouches have small radius rounded corners for a professional finish. To leave a clear border of laminate around your card, we recommend no larger than 2-1/8 x 8-1/4 size paper to allow for the sealed edge and rounded corners. Those who wish to punch a hole at one end and insert a tassel will want to shorten the 8-1/4” length unless they wish to punch through the paper too.
