Odor-eliminating toilet system that doesn't require changing for 3 days. - Brand: Unicharm - Product Name: Deo Sheet Odor Elimination Lab Toilet System - Features: Can be used for 3 days without changing - Included: Instruction manual - Size: Main unit set Thank you for viewing. This is a set of the main unit, one filter, and the instruction manual. I tried using it, but my pet didn't like the fluffiness of the filter and wouldn't use it at all. Although there was no actual elimination, I tried it once at home, so I'll consider it as "like new." I discarded the filter and toilet sheet because my pet stepped on them. This time, it's a set of one completely unused filter, the main unit, and the instruction manual. I disinfected the toilet unit with an alcohol wipe, but if you're concerned, please wash it with water before use. Retail price: 5283 yen, purchased at a home center. It will be shipped in the original box.
