Please read the description carefully! This is in the exact same condition as the previous cage. I used it for about 3 years to keep a hamster. The bottom part of the left door is broken, and I used it with masking tape. It comes with a running wheel and a thermometer. You can choose between a large and a small running wheel. For your reference... the large size was used by a golden hamster, and the small size was used by a Djungarian hamster. The thermometer needs a battery replacement. If you don't need the thermometer, I will discount it by 500 yen. In that case, please comment before purchasing.
