Cuisipro foam pump turns liquid soap into foam, reducing soap usage up to 75%. To use, pour liquid hand soap to the first line, then add tap water to the second line. The uniquely designed angle dispenses foam directly into the hand. A suction cup on the bottom keeps the dispenser from sliding on the counter. The non-aerosol pump mechanism stays clog-free. Easy to use one hand operation. Top shelf dishwasher safe.
