This is an inner mat from Whole Earth. I purchased it new and used it three times, but I'm selling it because I no longer have a need for it. It has been stored indoors. I do not have any pets, and I am a non-smoker. Inside the bag are two folded mats that are designed to be connected together for use. *The second picture shows the two mats spread out. I only photographed one mat due to the size of the room. The size when spread out is approximately 260cm x 260cm, although this is an amateur measurement. The thickness of the mat is approximately 1cm. Although it has been used only a few times, it is a used item, so please bid only if you accept it as is, with no claims and no returns. I will strive for a smooth transaction, so thank you for your cooperation.
