Purchased in 2021. This is a beautiful item, used only 7-8 times (about 10 hours total) by my son, but the brakes have some scratches. I've confirmed that the wheels light up when in motion. Please refrain from purchasing if you are overly concerned about minor imperfections. Items for sale: ● Inline skate shoes ● 1 instruction manual, 2 hex keys, blue laces (unused) ● Children's S-size protectors (elbows, knees, hands) and a black mesh storage bag My daughter's set is listed separately. If it's during a Mercari shipping campaign period, I will change the price for the entire set to 7000 yen, so please comment. 【Product Description】Copied and pasted below. ★ Uses smooth-rolling wheels and a lightweight, strong aluminum frame, ensuring safety and comfort. ★ No tools required; the size can be adjusted in 4 stages at 0.6 cm intervals with the push of a button.
