DUAL is a new concept of liquid hand wash using solid soap as packaging. It is designed to reduce the plastic pollution generated by waste bottles. After using up the liquid soap, user can remove paper wrapping and use the solid soap packing as hand wash. In the end, dispenser pump is the only component left and can be used in other DUAL soap replacement. The solid soap is made in a high density to make sure it does not crash when pressing the pump.
