This is a silicone mat from Pearl Metal. It has 2-3mm protrusions on the back, so it lifts slightly when placed. I bought it about two years ago for around 1000 yen. It's cute, but I haven't used it much. I've used it a few times as a trivet and as a non-slip mat for a cutting board. It's been kept in the kitchen. Please understand that it is not a perfect item. I will fold it in four and ship it via post.
