Nebula in Gyre:Mortise & Tenon M4 Four-Leaf EDC Mechanical Metal Stress Fidget Spinner

The M4 Tenon Spinner is a linkage spinner, when you spin it, the outer ring will drive the inner ring to spin. This spinner adopts the mortise and tenon structure which is a unique connection method in traditional Chinese wooden architecture and furniture. It achieves a stable combination between components through concave-convex interlocking. The precise mortise and tenon contact surfaces minimize frictional resistance, resulting in a longer rotation time. The sound is also not loud when you spin it so that is friendly will the players who work at the office.
