This is a Glass Harmony 450 Plus. I used it to keep a Djungarian hamster. I didn't see any chewing, but I think there are some small scratches because I used it for about a year. Also, the included wheel and water bottle are not included. I will include a separate wheel, a mushroom-shaped terracotta house, a Harmony toilet, and toilet sand (please see the photos for the remaining amount)! The toilet has been chewed a little around the entrance, and the wheel is a little dirty, but they are still usable ☺︎ I have washed it with water and disinfected it with alcohol. Instant purchase OK The box is included for the main unit and everything except the wheel.
