Roomy Grand Space Clear Wheel joint is blue. Used for about 3 years with a Djungarian hamster. There are bite marks, scratches, and stains that won't come off, but it can still be used. This is a used item. Please understand this before purchasing! Please check the accessories in the photos. Wheel: 17 cm The second-floor pipe and room are included as a bonus. If you don't need them, please let me know via message. This set is for Djungarian hamsters. I think it might be too small for Golden Hamsters. It will be shipped in a recycled box. Feel free to ask any questions. Small animal Hamster Roomy Cage
