Thank you for viewing. This item is brand new and unused. It has been opened once for photography, but has not been used. This running wheel has a transparent design, allowing you to clearly see your hamster. It blends well with your interior and comes with a stable stand for safe use. Recommended for small animals to relieve lack of exercise and stress. This item has been stored at home. There is a stain on the outer box (the contents are not affected). Instant purchase is welcome. We will ship quickly and carefully. #Honono'sShop 367 7121 0892
