This trivet was used at home and has small, chipped-off spots on the four corners of the tile surface. I had several trivets, so I used this one less and less, and haven't used it in the last year or two. Perfect for afternoon tea lovers! Material: Tile surface, cork backing Size: Approximately 15cm x 15cm I look forward to your purchase if you understand that this is a used item and has been stored at home.
