OLFA-Crafters Essentials Kit. This kit is perfect for both beginner crafters and those looking to stock up on the basics. The multi- purpose Touch Knife has a stainless steel blade that extends by sliding your thumb on the button and self-retracts once you let go.

It measures 1-1/4x12-1/2 inches with 1/8 inch increments. The 12x18 inch self- sealing Craft Mat extends blade life and protects work surfaces. Complete package contents include one Touch Knife, one Art Knife, one Ruler, and one Craft Mat. Imported.
