Blue inline skates that offer a comfortable fit with a combination of mesh material and plastic. - Color: Blue - Brake Type: Rear brake - Strap Type: Velcro - Design: Combination of mesh material and plastic Thank you for viewing. Since there is no box, I will wrap it in bubble wrap and ship it in simple packaging. These are inline skates for children. The size is S, and you can adjust the size by pressing the blue button. The size is indicated as 30, 31, 32, and 33, but the exact size is unknown. I think it can probably be adjusted to sizes from about 18cm to about 20cm. My son bought them when he was 17cm, and he played with them by adjusting with socks! The tires seemed to light up in the front, but they don't light up now. There are scratches from use, but you can still use them. There is also a hex key to tighten the tire screws. Please check the condition in the photos and consider purchasing if you are satisfied! If you have any concerns, I will add more photos, so please let me know! Thank you!
