SANKO Silent Wheel Flat 15 Clear, 15cm Diameter A quiet and lightweight 15cm clear exercise wheel. I didn't use this after purchasing it because it didn't fit the cage's height. My family also said it would be too small for our hamster. It's too small for adult Golden Syrian hamsters, so it's better for baby hamsters or smaller breeds like Djungarian hamsters. Suction cups are not included. Unused. Thank you. A quiet, clear flat wheel, 15cm in diameter, perfect for small animals. - Model Name: Silent Wheel Flat 15 - Size: 15cm diameter - Color: Clear - Features: Silent design - Included: Stand, bearings - Brand: SANKO - Model Name: Silent Wheel Flat 15 - Size: 15cm - Color: Clear Thank you for looking.
