Material: Natural diatomaceous earth (asbestos-free, safe to use). 【Diatomaceous Earth】Diatomaceous earth is a natural mineral formed from the fossilization of ancient plant plankton (diatoms) that accumulated on the seabed and lakebed over a long period of time. Diatomaceous earth contains a large number of micro-holes, has high compressive strength, is lightweight, and has good heat resistance, making it a suitable material for washbasins where water tends to splash. 【Excellent Water Absorption and Quick Drying】The diatomaceous earth tray has a porous molecular structure with countless fine pores inside, which quickly absorbs moisture on the surface. The absorbed moisture is immediately dispersed and evaporated throughout. It always stays dry. Wet soap, detergent bottles, toothbrushes, cups, etc. can be placed on it and will dry naturally in about 10 seconds. 【Antibacterial & Deodorizing】Diatomaceous earth soap dishes are alkaline substances that inhibit the growth and proliferation of bacteria. They can also absorb harmful substances such as aldehydes from the surrounding air and environment. Therefore, they can also absorb odors caused by bacteria and harmful substances. In addition to dehumidification, it also has functions such as antibacterial, deodorizing, anti-mold, and air purification. 【Multi-purpose】As a washbasin tray, it can be used to place toothbrushes, soap, bath products, wet dishes, hair accessories, etc. It can be used as a desiccant and antibacterial deodorant for dressers, shoe cabinets, and refrigerators. Of course, it is also suitable as a coaster. It has various uses, and you can use it freely. Thank you for viewing. I have kept it at home without using it after purchasing it the other day.
