This sponge rack is made of SUS 304 stainless steel, which is rust-resistant and durable, with a stable structure that is not prone to deformation. When the suction cups do not have sufficient suction power, they can be removed and placed in boiling water for several minutes to restore their suction power. During use, a small amount of water can be applied to enhance the adsorption effect. Before installation, the water tank must be cleaned and dried, kept smooth and free of debris. Then, the suction cups should be pressed firmly and fixed. It is recommended to measure the thickness of the sponge before purchasing to ensure a proper fit. The product size is 2.95 in. in length, 2.95 in. in width, and 0.78 in. in height. The open structure facilitates drainage, allowing the sponge to dry quickly and remain dry and hygienic. The overall design is compact, saving countertop space and suitable for various sink scenarios such as kitchens and bathrooms.
