What's duck spelt backwards? KCUD, a cleverly designed bin whose peddle to open and close does not protrude in an inconvenient fashion. KCUD is slim, the bin's lid opens and closes easily and comes with a clip built into the top of the bin that holds the garbage bag firm, in addition to wheels that make it easy to move. The bin holds 33 litres and is suitable for garbarge bags 45 litres plus. I bought KCUD bins for my personal use in Tokyo 4 years ago and can testify to their durability and functionality. Welcome to Japan's best selling intelligent garbage bin, KCUD. By the way it pronounced "cood".
