Kit 2.0 is an all-in-one bearing adapter for fidget spinners as well as a micro fidget spinner itself.
With all stainless steel construction, the Kit includes an r188 bearing, a housing the size of a 608 bearing, and a set of two 20mm buttons.
On its own, this is about as small and quiet as a fidget spinner gets. Very discrete and not distracting. It's also everything you need to swap into an existing spinner in place of a 608 bearing, breathing in new life and increasing spin times. You can even add a bit of weight by tacking a size 13 Tungsten ring to the outer core.
