I got this sample pack of peel and stick marble backsplash tiles because I wanted to see if I thought they would be good to use behind a sink in a small bathroom. I am definitely impressed in several ways. First, let me start by saying once in place, they are hard to adjust or remove. That being said, the finish is very realistic, and they really do look like high end marble tiles. To me, the best part is the "grout". Unlike actual grout that is porous hard to clean, these grout lines are a snap to clean because they are made of the same material as the tile - just wipe and done!
