Richway BIO-MAT Amethyst Size: Approximately 70 x 185cm Includes storage bag Purchased in 2010. Unopened and unused, stored at home for a long time. There are many cracks in the transparent part of the mat due to aging, and the amethyst is exposed. The mat is folded inside and wrapped in a plastic bag, so please be careful not to spill the amethyst stones when opening it. Please consider this as a junk item. Since it is unused, the condition is good except for the cracks in the mat. I operated it at the highest temperature setting for about an hour and confirmed that it warmed up gently. The exact temperature is unknown. Please consider this as a junk item. ✩Please consider purchasing only if you can use it for parts or have it inspected and repaired by a manufacturer, etc. The shipping method may change from Rakuraku to Yu-Yu.
