The Stafil 3-in-1 Corner Punch for Paper/EVA Foam, reference 779.17810-001, is a punch that rounds or decorates the corners of paper and EVA foam sheets with three different shapes in a single tool. Stafil is a brand of creative craft and DIY products, with a wide range of sewing, modeling, and decorating products, including felt, silicone molds, and craft accessories. Having three corner shapes in the same tool avoids buying three separate punches, making it practical for varying the finish depending on the scrapbooking, cardmaking, or EVA foam project. It's a great option for those who want to give a more rounded and professional finish to the corners of cards, invitations, or covers.
