Tiny7Ball Fidget Spinner

Tiny7Ball Fidget Spinner is a spinner designed for tiny hands. The metal balls on the perimeter distribute weight to keep the inertia going and ensure long spin times. I recommend using an oiled bearing, freesport makes a great bearing that can sustain inertia for extended periods. The balls are 1/2 inch spheres and can typically be purchased as "1/2 inch slingshot ammo".
