Mini 4WD bearing changer Compatible with 520 bearings [Taiando] (black) (3 colors)

Mini 4WDs are attracting attention from adults and children alike, as they can be enjoyed by parents and children together and can be customized by themselves. The rotational power of mini 4WD rollers can be improved by installing bearings. Bearings are consumable items, so as you continue to use them, their rotation will gradually slow down and require replacement or maintenance. In such cases, the bearing changer made by Taiando comes in handy! You can easily perform time-consuming replacements, making your work smoother.
