This is a set of 3 CORA IH silicone mats. They are popular on Rakuten! I am selling them because I accidentally bought the wrong size. There are 2 mats (image 2) and 1 mat (image 6), for a total of 3 mats. Size: 20cm Color: Gray The package of the 2-mat set was opened once to check the contents. At that time, a part of the side of the bag was torn. (Image 5) Although they are unused, please understand that they have been in someone's possession before.
