Heat-resistant kitchen mats protect against heat damage in various situations. Non-slip, providing stability. ● Size: Approximately 44cm x 30cm ● Material: Felt, Silicone ● Color: Black ● Other: Purchased online in November of this year and opened for use, but the size was incorrect. I repurchased a different size, so I am offering this one for sale. It was used for one day under a microwave. Please understand that this is a used item before purchasing. Thank you for looking.
