The Grind Machine is the first non-metal yo-yo to feature YoYoFactory’s patented triple bearing hubstack technology, which allows you to hold the yo-yo with your fingers while it spins. Is that not exciting for you? Then clearly you are looking at the wrong product. Combine the hubstacks with a wide modern shape and a textured grinding surface and you have one of the highest performing plastic yo-yos in the world.
For ages 8+.
