Small Do-it-Yourself Universal kit includes directions, a 3.75" X 5" sheet of grip material, a masking sheet to design and lay out your design, and cardstock to make a template.  Simply apply the masking to your firearm (or nearly anything else), trace the desired shape. and then either stick it directly to the back of the grip material to be cut into shape, or apply it to the cardstock to make a template to lay out the design on the grip material.  You just need a pen or marker, and a pair of scissors.

Available individually, or as a Three-Pack of Kits
