I'm obsessed with these suddenly. Use them as a dinner mat, use as a cutting board, use as a hot tray... these things are so handy. I got 2 of them in the bright green. I was thinking they'd be like any other silicone mat but these are even better!  Once you place them on your counter you have to peel them if you want them off. Which is a good thing, because they won't slip around. And they do t leave any residue behind as they are simply silicone.
