【Product Condition】 New, Unopened 【Product Description】 This is a replacement filter specifically for Unicharm's "Shoshu Lab" pet system toilet. It is compatible with the wide size (approximately 30cm x 40cm). 3 Days Odor-Free: The silver ion-infused filter suppresses urine odor by 99.9%. Always Dry: The hydrophilic agent prevents urine from remaining on the surface, keeping it comfortable at all times. Wide Type: Designed for wide-sized toilet systems, suitable for multiple pets or large dogs. I purchased this as a spare, but I have no use for it, so I am offering it for sale. Recommended for those looking for stock.
