Kao Toilet Magic Clean Bubble Pack in Water Mint is a refill pouch for the Japanese toilet bowl cleaner that spreads dense foam around the bowl and works while you leave it for at least five minutes. The citric acid formula is made for inside the bowl, helps deodorize, and supports routine care against black stains, urine scale, and yellowing, while the upside down spray design also makes it easier to reach under the rim when used with the matching bottle. It is best for households that want fast regular cleaning with a crisp, fresh scent.
