Amazing absorbency that dries instantly! A wonderful natural material nurtured by nature. Dries quickly, always feeling smooth! <What is diatomaceous earth?> Diatomaceous earth is formed from the fossilized shells of diatoms (plant-like plankton and algae) that accumulated in the oceans, rivers, and lakes of the Earth approximately 10 million years ago. It has a surface with minute pores; the average particle size is 0.05mm, while the ultra-fine pores are 0.1μ~0.2μ in size. These pores absorb and release moisture, providing an autonomous humidity control function. Diatomaceous earth has been used for a long time as a material for shichirin (Japanese charcoal grills) and bricks. In recent years, taking advantage of the autonomous function of diatomaceous earth, it is also used as a wall material, and also as a filtration material for beer and sake.
