Nakabayashi A4 size Slide Cutter Slim NSC-SA4 This is a replacement cutting mat for the Rotary Cutter Compact NRC-CA4. It comes in a pack of 3, and each mat can be used for cutting on both sides, left and right, for a total of 4 cutting surfaces, allowing for 6000 cuts with the set of 3. I am selling this because I mistakenly purchased the wrong size for my rotary cutter. I hope someone who needs it will find it useful. Thank you for looking.
