Corner Rounder Punch, 4mm Corner Cutter for Paper Crafts, Laminator, Cardstock, DIY Projects, Photocards, Card Making and Scrapbooking, Black

I ordered this item for one simple function, to round out the corners of paper. This does NOT work at all. The blades are dull and when I insert paper and press down, it does not cut, it sort of bends and then tears when I extract the paper. The product is shoddily made, it took a month and a half to arrive from China, and it's not worth a penny, much less whatever they're charging. Also, the edging barely fits a corner of a normal sheet of paper. I don't know how they're allowed to sell something like this on Amazon. Totally disappointed. Not even worth returning. Garbage.
