This is a Harmony 450 glass cage. Size: Approximately 46.8cm wide x 31cm deep x 28.2cm high Harmony Wheel DS17 [Safety & Silent] ● Quiet bearings reduce noise. ● Silicone cushions on the bottom and back of the stand reduce rattling. ● Equipped with brake pads to prevent the wheel from spinning too fast, ensuring safety. ● Seamless design is gentle on hamster feet. The wheel has been changed from the original set. I kept a Djungarian hamster in it. The door latch has some wear. There is a crack on the outside of the case, on the side. I have thoroughly cleaned it at home, but it is a used item, so please understand this before purchasing.
