Both of these exercise wheels are in great working order. The green one is 6" in diameter and has a little paint missing on the metal stand as seen in the photo. The Blue Saucer is 7" in diameter. These size wheels are both best suited for either dwarf hamsters or mice. If you have a Syrian/Fancy Hamster, you'll want an 8" or bigger. Both of these wheels, while used have been ran through the dishwasher and sterilized. Ships out within 24 hours from Michigan via first class mail.
