This silicone mat is about 12cm x 15cm. It allows you to amongst other things to be able to mirror stamp with confidence. Simply ink your stamp up and stamp it onto the mat then press your piece of paper onto the stamped image. The ink will be picked up onto the paper as a mirrored version of your original stamped image.
This mat can be cleaned easily by either wiping with a cloth or warm soapy water. It is flexible, light weight taking up minimal space in your crafting area.
This is a green mat but it is also available in pink or green so please see other listings if you want to purchase other colours.
