The GoBiggeR Sinian is a hand-worn multifunction metal fidget. Flick or swing it to trigger the central tuning-fork core for a strong impact response and a clear, lingering ping, then chain the motions into smooth combos. A ratcheting finger-ring and a dual-state rotor round out the play.

Highlights

• Designer and series. From GoBiggeR, a studio that started in portable displays and now makes premium CNC metal fidgets; the Sinian is its signature piece.
• Mechanism and feel. A central tuning-fork core, triggered by a flick or swing, delivers forceful impact feedback and a crisp, ethereal ping; the ratcheting finger-ring adds dense, tingling mechanical feedback through every swing.
• Dual-state rotor. Closed, the rotor gives a soft, magnetic, jelly-like resistance; opened, it becomes a high-speed spinning gyroscopic rotor.
• Build and customization. Precision metal across aluminum, PEI, titanium, stainless steel and zirconium, with accessories built for visual DIY. Internal parts use thread-lock and are not meant to be taken apart.
