1. Safe Environmental ProtectionThis foaming soap dispenser is made of sturdy PET plastic (BPA ), , non toxic, odorless, harmless and reusable. It is not easy to be damaged and has a long life. 2. The set includes 4 empty square foam soap dispensers, 2.56 x 2.56 x 7.28 inches (65x65x185mm), which can hold 15 ounces of foam soap solution for a practical and convenient cleaning. 3. Leak DesignOur foaming hand soap dispenser comes with a plastic buckle and tight threads inside that can lock the pump and prevent any leakage. So you can ly put the foam pump bottle in the bag without worrying about liquid leakage. Besides, we have also designed a groove at the bottom, which greatly improves its stability. 4.
