Here is some information about House of Six Cats:
Coasters are printed on a state of the art, self adhesive, material so it creates a permanent bond with the tile. This means there is virtually no transitional lip from print to tile. As a final layer of protection, there is a thin, matte, UV laminate applied to the face of the material which ensures they will stay water resistant, smudge resistant, stain resistant and scratch resistant. And because it is a UV laminate, these can be left outside with no fear of the image fading! Each tile measures 4.25” x 4.25" and is backed with black foam that ensure against table abrasion and sliding.
I am honestly very impressed with these coasters and will be getting tons of use out of my new veggie ones!
