Amazing mat!
Love it! The texture is nice and smooth, and it didn't take much fighting to get it to lay flat. I appreciate the double-sided nature with a different color on either side-- I end up using the white side more because it helps me see the colors of the polish against the nail better. I recommend making sure the holes on the strap are open before using it just to save yourself the time of fighting with the snap to push it through.

True to color and seems like good quality but even after a week the corners still won’t lay flat

Durable product
Great mat for desk or table for girls that love doing their own nails, or just to use to keep an area clean for a project. Can be rolled up and easily transported. Can switch sides as well! Great product and easy to clean.
