This stone drainage pad is made of silica soil and can quickly absorb spilled water and evaporate within a few minutes. It can eliminate the damp environment that promotes the growth of dirt, prevent the generation of odors, and ensure the cleanliness and hygiene of the sink area. The closed grooves can prevent the spilled water from seeping onto the countertop. At the same time, the deeper and wider grooves can accommodate and absorb more spilled or residual water, keeping the countertop dry at all times.
