THE CORE is a sci-fi-inspired tuning fork spinner jointly launched by SPINMOON and INSITU EDC. Inspired by ancient weaponry and mecha design, it combines a modular build with distinctive acoustic feedback for an immersive EDC fidget experience.
16-Piece Modular Design: The one-piece modular structure can be disassembled into 16 individual 3D modules. Multiple surface finishes can be combined for a personalized look.
Tuning Fork Resonance Chamber: Wind-cutting blades, a tuning fork recirculation structure, and a hollow acoustic chamber work together to produce metallic, mecha-inspired sounds during rotation. Six energy blocks around the lock bolts direct kinetic energy toward the central bearing.
Balanced Weight & Flick Feedback: Ultra-thin bearings concentrate weight inward, while the hollow construction helps retain weight and creates a bouncy flip feel. Smoothly chamfered blades feature 30° trigger points for comfortable fingertip flicks.
Spin & Acoustic Feedback: The blade-tip tuning fork geometry interacts with airflow during rotation, delivering tactile vibration and resonant sound as you fidget.
