Corner Rounder Punch 10mm - SDI - Card, Photo & Paper Crafts

SDI corner rounder punch with a 10mm radius, for trimming sharp square corners into smooth, rounded edges on cards and paper.

A corner rounder is a small punch that trims the sharp square corner off paper or card and leaves a clean, rounded curve. Slide the corner into the slot and press, and it cuts a neat 10mm radius every time. Rounded corners look more professional, are safer with no sharp points, and are less likely to bend or fray. This 10mm size gives a larger, softer curve that suits tags, big cards and laminated sheets.
