Thank you for viewing. This is a water-saving device, LossCut, that can reduce water usage in flush toilets by over 30%. I used it for a few days, but it didn't suit my household, so I'm selling it. I used it for a few days and cleaned it, so it's in a clean condition. I'd like to sell it to someone who wants to try LossCut but is hesitant, or to someone who understands that it's a used item. The box will be folded and shipped via Takkyubin Compact.
