CHENYU Syntony

3-in-1 Functionality: Combines buckyballs and mechanical structures for versatile play: one side features dual mechanical tracks with distinct click feedback; the other side holds magnet-driven resonant buckyballs. Its hollowed-out construction boosts vibration sounds, with bouncing buckyballs creating clear frog-like chirps and strong tactile feedback. Take out the buckyballs, and it turns into a pure mechanical slider right away. DIY spring bead tuning lets you adjust the tone and handfeel, meeting multiple stress-relief needs in one device.

Versatile Styling: Lightweight, portable, wear-resistant and drop-proof, it works perfectly for fidget beginners. Sized to fit across your tiger’s mouth, match fingertip width, and deliver a substantial grip, it fits the natural pinching motion of thumb and index finger perfectly. It comes with a detachable lobster clasp, usable as a knife pendant, strung as a necklace or completely removed for minimalist everyday carry.
