This EVA foam play mat is a high-temperature foamed product with a few bubbles on the surface. Small defects are normal. It may have a slight smell after production, but it is the smell of new material and does not affect the use. To remove the smell, wash the product, ventilate and dry it before use. The mat is super flexible, easy to assemble, and can be used for parent-child interaction. It is made of non-toxic and environmental protection materials.
