LED YO-YO SIDE CAPS
Spin-activated lights for your butterfly.

There aren’t many low-budget ways to customize
one’s yo-yo. The most common ones are painting
or dyeing; both look great, but they’re limited: paint
chips off, and dyeing is only for plastic yo-yos.
Yo-yo with concave sides. For more space and greater
stability, pick one with a flat hub and inner rim.
