Joint mats made of ethylene vinyl acetate, set of 58, size 30cm x 30cm, featuring beige and dark brown colors. - Size: 30cm x 30cm - Quantity: 58 sheets - Colors: Beige and dark brown - Material: Ethylene vinyl acetate (EVA) Thank you for viewing. I purchased these from a store about 6 years ago. I can't remember if it was Nishimatsuya or Toys "R" Us. I wiped them with disinfectant wipes, but there are still some stains, scratches, and discoloration that couldn't be removed, so there is a sense of use. I hope you will understand that these are used items before purchasing. There is no box, so I will ship them in a recycled cardboard box. #JointMat #Baby #Infant #Educational #PuzzleMat #Simple #ColdProtection #Soundproofing #FallPrevention #FreeCombination
