I have brand new countertops, and don't want anything to scratch them. I got these so I could put them on all of the stuff that I keep out, like cookie jars and Canisters. They work great. These are a little thick for my needs, but they do a good job. There are enough of them, that I can put them on the holiday decroations that I always put out and I don't have to worry about the kids and grandkids scooting them accross the countertops.
