For the high-function Moist Lotion with very delicate ingredients, this product: a unique refillable pump bottle is designed to keep the pump tube unexposed during the refill process to ensure hygiene and prevent spillage. The cartridge system with a long tube in the bottle works to refill easily without direct touch of the lotion and maintains its quality. The pump with a short tube is inserted to open the new bottle. Unlike other conventional products with a unified pump and long tube, it prevents the lotion from having unwanted bacterium. As a result, high level of hygiene and the sophisticated/easy handling during refilling are achieved.
