Only one corner. Bought as a gift. Disappointing.** A: Never have I gotten one when all three corner sizes work. Typically the biggest size works okay for a while. **Q: Does it work on laminated cards** A: It can, but it’s not consistent. I’ve tried using it on 3mm laminate and at first it worked, but after a while the blade seemed to weaken. Then it work on one or two corners, but not on the rest and I’d have to cut it with a pair of scissors. **Q: Would this product work on thin chipboard (14-ply, approximately 0.05 inches/1.27 mm thick)?** A: I have used this paper corner rounder on card stock and laminated card stock. It is able to work on card stock paper that is laminated with 5 mL laminating sheets. The entry point to insert items is very small and thin. It seems to work best with thin paper. **Q: I would like to round the edges of iron name tags. I will be using a Brother label maker w/ a fabric iron-on tape cartridge. Will it work?** A: I have only cut 2 pieces of normal printer paper at a time. If your metal is thin enough it might work. But not sure how long the cutter would stay sharp if you cut metal with it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Buen producto *by I***A on 28 January 2026* Resistente !
