Product Description The Fidget Spread (Pillbug Youth) features a mecha-inspired design with a heavy, rounded shell. Its central body is crafted from aluminum using precise CNC processing, while the outer shells are made of multiple alloys with painted armor finishes for a striking appearance. The spinner offers an open-shell mode with interconnected mechanics: when one shell spins, it drives the others, creating smooth internal and external linkage rotation. Equipped with multiple grooves for tritium gas tubes, adding them produces a visually stunning, glowing warp effect, enhancing both aesthetics and interactive play.
