I have three sets of mats for a 6-tatami mat room. I bought them from Tansu no Gen. They are a set of 3 boxes. I bought too many and am having trouble finding space for them, so I'm hoping someone will buy them. These are waterproof and cuttable PE resin joint mats, 59cm in size, perfect for children. - Size: 59cm - Thickness: 1cm - Waterproof: Yes - Material: PE resin - Cuttable: Yes - Color: Beige Thank you for looking.
