Cleans away water stain汚れ! Also usable on plastic Removes stubborn "water stain汚れ" from bathrooms, faucets, and washbasins, leaving them sparkling clean. Effectively removes "black grime" from bathtubs and "sliminess" from drains. Employs ultra-microscopic particles of 10 microns or less, so it won't damage bathroom materials, allowing for safe use. Cleaning Mechanism: The cleaning agents lift the dirt from "water stain汚れ," "black grime," and "sliminess" in the bathroom, and the abrasive component "HA component (hydroalgerite)" removes it completely. Features a natural herb fragrance for a refreshing cleaning experience. ▼ I've used various cleaning products, from cheap to expensive, but this product cleans the dirt by far the best. Please give it a try. ▼ It will be shipped via Yu-Packet Post, but because the size barely fits through the mail slot, it will be placed directly into a reinforced delivery bag with tape, which may cause scratches on the container. Please purchase only if you understand this. ▼ Currently discontinued and only available online, the price will likely increase further and become difficult to obtain. Price is not negotiable.
