Super dreamy and beautiful roller skates, perfect for beginners and those who want to easily learn roller skating! Comfortable Fabric - The surface of girls roller skates is made of high-quality PU leather material, which has good resilience and better maintains novelty and fullness. The velvet fabric inside is very comfortable, soft, breathable, and comfortable to wear. High Quality PU Wheels - The wheels of roller skates are made of high-quality crystal blue and crystal pink PU wheels, rather than ordinary PVC wheels. They have higher wear resistance, shock absorption, and strong grip, making the wheels more comfortable and smooth during movement. When the wheel rotates on the ground, friction and power are generated, causing the wheel to flash! It only flashing when the wheel slides. And the wheels are stationary, they return to their original color. (No battery or power required) If you want the wheel to not flash when sliding, you just need to remove the black circular magnetic core inside the wheel. If you want the wheel to flash and then put the magnetic core back on the wheel. Built in ABEC-7 bearings, with strong carrying capacity, classic double row roller skates are safer and more stable than inline roller skates. There is a support column in the front for better control and quick braking.
