This is a soap box with brush that can reuse the soap water. The soap box is divided into two parts, the tray at the top is used to store the soap; the brush is in the middle; and the tray at the bottom is used to store the soap water. The structure of the tray is easy for ventilation, which can keep the soap dry and clean. At the same time, when we use the brush, the soap water in the bottom tray can be used as cleaning fluid to reduce the usage of clean-up agents. It is convenient and environment friendly--that's killing two birds with one stone.
