Lava Stone Bath Mat Hard 40

This bath mat is made from lava stone (volcanic rock), a highly absorbent natural material. The moment you step on the mat, it absorbs moisture pleasantly. We want you to be surrounded by things that you use in your daily life and that you find comfortable. We create our products with this thought in mind, so that they can be a subtle addition to your life. The pores in lava stone, formed by natural activity, have the ability to repeatedly absorb and dry water, and they also have a natural moisture-regulating function. They absorb moisture when humidity is high and release it when it is dry, allowing the surface to always remain dry. Source: https://www.amazon.co.jp/
