A compact, JoJo‑inspired Gyro Steel Ball replica engineered with a clever modern twist. Instead of relying on internal bearings, this version uses a hidden retractable ID badge reel to create the illusion of Hamon‑level spin.

The ball itself is smooth, symmetrical, and weighty, echoing the classic Steel Ball design with engraved panel lines and a polished metallic finish. When the badge reel cord is pulled and released, the ball whips into rotation, snapping back with a satisfying mechanical recoil that mimics Gyro’s signature throwing technique.

Perfect for fidget‑style play, this design blends sleek JoJo aesthetics with a simple, durable mechanical trick that makes the ball feel alive in your hand. It’s a fun, kinetic prop that captures the spirit of the Spin without needing complex internals.

Instructions: 

Remove the metal piece of the badge reel and insert it in the hole. Pull the string so it sits outside the ball. Insert the two pegs and add glue to one side of the sphere. Glue the two spheres together making sure the string is outside. Ensure drying time for the glue before you handle roughly.
