Shirotasokuinui vermiculite diatomaceous earth bath mat compact made in Japan

Wow! This clay mat arrived within 2weeks in perfect condition. Functions as described moisture disappears within seconds. Others stated these clay mats are heavy not so. It is firm like compressed cardboard but not cold to the touch and wow dries like magic! I rinsed it before first use and as soon as the last drops of water rolled off it was dry. The instructions are completely in Japanese, but I read reviews of other clay mats not to clean with solutions just rinse and stand to dry. The dimensions of this compact size mat are 16"x22"X1" no tripping over it because of the curved edges and it's so compact it doesn't get in the way beyond the step out point at the tub. So happy I too the chance and tried this. Great clean alternative to cotton bath rugs. If I notice anything noteworthy in my continued use I will repost, but so far I'm excited about this really cool alternative. Perfect size for small bathrooms!
