The mat is very sticky and can be used many times. If you keep the blue backing paper and place it on the sticky surface between uses, dust and other particles wont get stuck to it and it will last longer.
I love the new mats! I didn't have to prime it/cure it/prep it or any of that. And now the adhesive is only in the 12x12 cutting area so I don't have to worry about any strips coming off the side and it being sticky under the roller. The only improvement I'd made would be to make the blue cover a little bigger so you're always sure to cover all of the adhesive. Other than that, it's great!!
I love the Silhouette Cameo, just wish these mats lasted longer. lol Best price here though! Thank you for everything, customer service should have a rating and I would rate you 500%!
