Product Description Designed by JOY EDC, the BGM fidget recreates the look of a vintage cassette player, featuring dual speakers, vibrant ring-shaped ambient lights, and a transparent casing that showcases internal circuitry—blending retro charm with modern visual flair. Its half-way fully automatic rail switching allows seamless transitions between common cross sounds and dense pure “ding” sounds without disassembly, and it supports multiple gameplay modes. Note: avoid using springs over 0.3 mm diameter or high-hardness springs on the direct push surface to prevent strip deformation. The rotor side includes a ding-ding rotor and a Buckyball rotor. The ding-ding rotor produces adjustable, distinct sounds (disassembly required), while the Buckyball rotor delivers powerful impacts and simulates audio speaker effects. A titanium engraved magnetic screw cover adds refined aesthetics and conceals assembly details for a polished, collectible finish. Specifications: Size: 60 x 22 x 14.8mm Weight: Titanium: 62g
