Nice enough mat, I guess, but the statement that they will cut the inside to your specifications is bogus. I followed all instructions and got an email reply saying they would cut it...no problem! Not true.
$20 down the crapper. Don’t waste your time or money.
EDIT: after posting this review, I contacted seller and provided pictures of the mat that was cut wrong. They very quickly got back to me, apologized, and sent me a new mat that was cut properly (no cost, and no need to return the wrong one.) I’m satisfied fully. My art is FINALLY up on the wall.
