Small animal cage set with a reversible heater and wood mat. - Harmony Glass Cage 450 - Heater type: Reversible Heater L size - Heater size: Approximately 320 x 215 x 14mm - Wood mat, 15.5L (new) - Accessories: Toilet, water bottle, wooden block, egg-shaped ball Thank you for viewing. I believe everything is included except for food. Everything except the wood mat is used. The included plastic stairs were discarded because the hamster couldn't climb them due to slipping. Instead, I've attached homemade wooden stairs to make it easier to climb. There are two exercise wheels, medium and small. (One base) There are some scratches and stains in places. There are holes on the side of the cage for attachments, but three of the caps for those parts are missing. The photos show everything. I used it for several years, but there were no particular problems. If you understand, please consider purchasing.
