There's nothing like a 28mm cutter to make using my favorite notions ever, the Clearly Perfect Slotted Trimmers, as easy as possible. They fit right in the little slots and cut those dog ears off easy as anything. I love using these cutters with Sue Pelland's rotary cutting templates, too, and often find myself reaching for this size even when I'm just cutting out squares. So much control and easy to pack for classes.
Rotary cutter comes with one blade. Refill blades are in a 2 pack.
