The SAN WEN is designed by Sequence.This is a purely mechanical structure tuning fork haptic coin,and can produce dual tone.
Striking the tuning fork can make the sound directly,without the body of the impact to transfer kinetic energy, so that it is easy to play with it and has a clear sound.
Tone and internally mounted, held at random will not affect the sound effect, but also through the replacement of the tuning fork, to send out dozens of tones.
Due to the installation of two different specifications of the tuning fork, can be issued in two tones, it can be rotated through the positive and negative to simulate a similar minute repeater watch chime sound effect, that is, the product is named: SAN WEN.

Isabella B.★★★★★
I keep it on my desk and find myself flicking it whenever I'm thinking through a problem. The mechanical tuning fork design means there's no battery or anything to charge, which is exactly what I wanted.
Olivia K.★★★★★
I wasn't sure what to expect from a mechanical coin, but the tuning fork inside gives off a surprisingly rich dual tone that lingers just long enough to feel satisfying. The purely mechanical build makes it a neat little fidget that doesn't need batteries, which I appreciate.

The dual tone it produces when you strike it is cleaner than I expected for something this small, and the mechanical tuning fork design feels solid in the hand. I've been fidgeting with it all day, and the vibration from each strike is a nice tactile reward.
