No markings. It was hardly used before outgrowing it. Used about 2 or 3 times in the park, so: ⭕ Tires are dirty. ⭕ Sides are clean. It's in good condition and a shame to waste, so I'm selling it. I couldn't completely remove the dirt from the tires, so I'm selling it at a lower price. There are protectors with the same pattern. Roller Skates 20 21 22 23 Inline Skates juicy
