For sale: Used small mouse/rat experimental breeding cage. 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 please understand that there may be dirt, scratches, discoloration, scratches from mouse claws, and areas chewed by teeth. There are no problems with normal use, and we have confirmed that there are no cracks, holes, or leaks. As you can see, the rubber part of the bottle lid is dirty, but it has not come off over time, even though it was cleaned with a brush every time the water was changed. Since this is equipment used by animals, it has not been cleaned 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 large, and the shipping cost will be high, 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 mice, they cannot reach the lid even when they become adults, so they did not push up the lid. In the case of rats, they may push up the lid when they get larger, 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.
