Prevent your rulers and cutting mats from slipping with Sariditty's Pretty Glitter Grips. Stick these glittering grips to the back of templates, rulers, and mats to stop irritating and dangerous shifting. They can be reposition as required and each Glitter Grip measures between 1/2" and 7/8". The Cherry Blossoms and Circles come 30 to a pack, while the Butterflies hold 27. To maximize the effectiveness of the Glitter Grips, it's recommended that you use a three-point pressure system.
