This is the best masking product on the market I do believe! Judikins makes it and I LOVE using it for masking. I no longer have to stamp my images in just the right spot on a sticky note because the entire back side of this paper is sticky. Many times I just put my image mask in the lid of the box that houses the stamp I've made it for and I can use it many times before having to make a new one. I love this stuff!
