This is a food dispenser. It can store dry foods such as cereal, snacks, nuts, and pet food, and dispenses them in the desired amount. It works by dispensing a set amount when you turn or push the handle. It helps prevent moisture and insects from entering, and preserves the flavor of the food. It seems it can be disassembled and washed thoroughly. I used it for about a year to store pet food, and it was very convenient and helpful! The dispenser outlet has a lid, which prevents insects from entering. This is a used item, so there may be some lingering odors. Please refrain from purchasing if you are sensitive to this. There are no instructions or outer box. Also, please understand that this item has been stored at home and inspected by an amateur. ※ As shown in the image, it is tilted downwards. It might not tilt downwards if you insert it with a click, but I'm not sure if it will be level. I was using it with cardboard inserted.
