Description

Experience endless tactile focus with this Kinetic Geo-Spinner! Designed around an intricate triangular outer housing with a planetary gear movement, this fidget toy offers an extremely smooth and long-lasting spin with satisfying mechanical feedback.

Versatile by design, the spinner can be used with or without the protective top and bottom covers—run it bare to watch the exposed gear mechanism in motion, or attach the covers for a sleek, finished look!

The clean 3-layer modular assembly uses snap-in faceplates held together by precision locking pins to keep the internal gear meshing perfectly aligned.
