This is from when I used to keep a hamster at home. The size is 45cm wide, and it's a GEX product. I accidentally dropped it while cleaning the cage, and there are damaged areas as shown in the photos, but there are no problems with normal use. Please consider purchasing with the understanding of this condition. Also, I will include the accessories in the attached photos (ceramic house, etc.) and unopened bedding. Recommended for those who are keeping a hamster for the first time. Please also take a look at the heater I used when I kept the hamster, which I am also selling.
