Size: Approximately 20cm wide, 32cm deep, 13.5cm high Materials: Body: Polypropylene, Lid: Stainless steel Bottle Capacity: Approximately 200ml This is a used item, so there may be stains, scratches, discoloration, and marks from a mouse's claws and teeth. We appreciate your understanding. There are no problems with normal use, and we have confirmed there are no cracks, holes, or leaks. The rubber part of the bottle lid is dirty as you can see, but it has not come off over time despite being cleaned with a brush every time the water was changed. Since this is equipment used by animals, we have not cleaned it with chemical detergents. Also, the rubber part has become quite thin, so please understand that the bottle is only an extra. If we pack it in a cardboard box, the size will become larger, and the shipping cost will be higher, so we will ship it wrapped in bubble wrap. The photos are representative. Please note that the actual product shipped may differ. The lid does not have a locking mechanism, but in the case of a mouse, even when it becomes an adult, it cannot reach the lid, so it did not lift the lid. In the case of a rat, it may lift the lid when it gets bigger, so we used double clips (large) sold at 100-yen shops to fix both ends. We may have more stock than the number of items listed, so please contact us if you want more than the number of items listed. This is a used item, so please understand the above.
