Interestingly, the "Xcut Corner Rounder Punch - Large" (10mm radius) appears in Kitchen & Home and the "Xcut Corner Rounder Punch - Small" (5mm radius) appears in Toys & Games. Apart from the radius, they are of identical construction. I purchased one of each, wishing to round the corners of laminated sheets and light card (160g). While the size of the cards is immaterial to the punches, I found the small punch was ideal for credit card size and the large for A4, both working perfectly and very convenient in use. Clippings are retained in a small, easily emptied compartment. Only time will tell how easily they blunt or fail, but gut feeling suggests both will give good service. I also purchased a "Button Corner Rounder Punch - Regular" by a different manufacturer and from a different source which supposedly does the same job. In contrast to the sharp cuts of the Xcut punches, this rounded the corners but left the laminating material hanging.
