I purchased this for a sugar glider, but it was too big, so I'm selling it. It's unused, but there are scratches on the outside of the wheel from when I installed it in the cage. Please understand that this is a used item before purchasing. There are no issues with its use. All parts are included. I will ship it in the same condition it was sent from the store (it was only in a bag, not a cardboard box). Thank you.
