Number of times used: 3 times at an indoor skating rink, 8 times at a park. There is some scuffing mainly on the heels and toes from braking, but otherwise, I think it's relatively clean. (Please check the photos for details) Size adjustable between 23-26cm. If you'd like, I'll include a Rollerblade helmet (54-58cm), protectors (knees, elbows, hands), and a storage bag (Victoria).
