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's feet. The wheel has been changed from the original set. I was keeping a Djungarian hamster. There are marks on the outside of the top where I used clips to prevent escape. I have cleaned it thoroughly at home, but it is a used item, so please understand this before purchasing.
