MUYI, also known as NAYICI, brings creativity and mechanical innovation to the world of EDC fidget toys. From satisfying fidget sliders and haptic coins to precision spinners and multifunctional pocket tools, the brand offers a diverse collection designed for different playing styles and preferences.
What makes MUYI stand out is its attention to mechanical details, combining distinctive designs with engaging tactile feedback. Whether you enjoy smooth sliding, satisfying clicks, or intricate mechanisms, there's plenty to explore.
In this guide, we'll take a closer look at the MUYI collection available at M-EDC, covering each product's key features, pricing, and availability to help you find the right addition to your EDC collection.
Start Here: The Four Standouts
If you don't want to read the whole guide, start with these four — they're the most distinctive pieces MUYI makes right now.
Shake Particle — $99–$209. A dual-layer magnetic pendant built aroun
d levitation and oscillation — at rest the two layers hold a floating balance; shake it and they come alive with customizable magnetic feedback. It also connects with Artillery (below) for expanded modular play. The most un
usual fidget in this guide, and the hardest to put down.
Soundwave Nano — $219. A premium slider for collectors who want something more distinctive than the entry models. Compact, engineered, and unmistakably MUYI — the name gives away the design language.
Artillery — $235–$379. A modular all-in-one combining magnetic, mechanical, rotational, and sound-based feedback in one structure, including a magnetic catapult mechanism. It also connects with Shake Particle and Cyber Mecha modules, so the two can grow into a bigger system together. For people who like their fidgets with moving parts and mechanical depth.
Demoman — from $259. The flagship super-hybrid: five functions (ratchet, spinner,
egg-push slider, linkage mechanism, and component expansion) in a single piece. If you want one M
UYI piece that does everything, this is it.
The Sliders
TOFU — from $59.90. The entry point into MUYI. A straightforward fidget slider at the most accessible price in the lineup. If you're curious about the brand but don't want to spend triple digits to find out, start here.
ERASER CORE-07 PRO — $99–$159.90. The mid-range slider and the best all-rounder of the bunch. Note: the non-PRO ERASER CORE-07 is currently sold out, so the PRO is the one to get if you want this design.
Soundwave Nano — $219. A premium slider for collectors who want something more distinctive than the entry models. The name gives away the design language — compact, engineered, and unmistakably MUYI.
The Multifunctional Pieces
This is where MUYI gets interesting. These aren't just sliders — they're pocket tools that happen to fidget beautifully.
Bomber — $199. A multifunctional fidget toy with real presence. Big, mechanical, and satisfying — the kind of piece that lives on a desk and gets picked up constantly.
Artillery — $235–$379. A step up in size and complexity, with multiple configurations depending on the variant. For people who like their fidgets with moving parts and mechanical depth.
Demoman — from $259. The flagship all-in-one. Demoman packs multiple fidget functions into a single piece, and the price range reflects the different materials and configurations available. If you want one MUYI piece that does everything, this is it.
The Haptic Coin
Amiable Milk Cap — $90–$125. MUYI's haptic coin, and a good reminder that the brand isn't only about sliders. If you prefer coin-style fidgets — rolling, flipping, and stacking — this is MUYI's answer, and it pairs well with any of the sliders above. (We also featured it in our Best Fidget Coins for Adults (2026).)

- Around $200: Bomber ($199) for a multifunctional desk piece, or Soundwave Nano ($219) for a premium slider.

- Coin lover: Amiable Milk Cap ($90–$125).
Currently sold out, so don't get your hopes up: ERASER CORE-07 (non-PRO), CORE WAVE, and Bone Breaker (the spinner) are out of stock at the time of writing. If one of those is the one you wanted, the closest in-stock alternatives are ERASER CORE-07 PRO and TOFU.
