21cm Hamster Wheel with Stand, Silent Design - Brand: GEX - Model Name: Harmony Wheel 21cm - Size: 21cm - Features: Silent Design I purchased this wheel online when I got my degu, but the one I originally ordered didn't arrive, so I bought this one in a hurry. I used it a few times until the other one arrived. The size is too small for a degu, so I'm selling it in hopes that someone who has a hamster can use it ( ¨̮ ) Thank you!
