Start With the Feedback You Want
The Nayici (Muyi) Core Wave-03 is a multi-mode slider built around a dual mechanical and magnetic feedback system. If you are shopping for a Nayici EDC fidget, the key decision is not just the material—it is how the slider feels and how much you want to customize it.
The Core Wave-03 features both vertical and horizontal tracks. A Buck magnetic ball linkage lets the magnet track drive the Buckball, triggering four magnetic vibrations with each push, combined with mechanical paragraph feedback. That means you get two distinct sensations in one compact tool.
The default factory setup has 10 segments (“paragraphs”), but inserting pins upgrades it to 20, making the feedback feel denser and crisper. You can also configure it in mechanical+magnetic mode, pure mechanical mode, or pure magnetic mode.
Core Wave-03 Specs That Matter for Buying
- Nayici (Muyi) Core Wave-03: Dimensions: 50×25×19mm A pocketable size that fits comfortably in hand and in an EDC pouch.
Nayici (Muyi) Core Wave-03 - Nayici (Muyi) Core Wave-03: Weight: PEEK: 34g; Titanium: 48g The PEEK version is noticeably lighter, which matters if you carry it all day or prefer a lighter feel.
- Nayici (Muyi) Core Wave-03: Three luminous tube slots: one for a 2×12mm tube and two for 1.5×6mm tubes, no glue required. You can add tritium or glow tubes without adhesive, so customization is straightforward and reversible.
PEEK vs Titanium: Which Material Fits You?
The Core Wave-03 is available in PEEK and titanium. PEEK, known as “soft gold” in plastics, has triple the impact resistance of titanium alloy and a warm, jade-like, skin-friendly texture. The inner PEEK liner is naturally lubricated, so it feels smooth without extra oil.
The Dune PEEK Edition is a limited release that combines PEEK with cyberpunk line patterns. To suit PEEK’s unique characteristics, the internal springs, beads, and Buckballs have been retuned for optimal tactile feel, delivering stronger feedback than metal. If you want a lighter, warmer-feeling slider with a distinctive look, PEEK is the clear choice. If you prefer the heft and durability of metal, titanium is the way to go.
DIY Customization: What You Can Change
- Modes: Switch between mechanical+magnetic, pure mechanical, or pure magnetic using the included accessory kit.

Is the Core Wave-03 Worth It?
At USD 44.50 (compared to a catalog price of USD 89.00), the Core Wave-03 offers a lot of tactile variety for the money. The dual feedback system, three configuration modes, and extensive DIY options make it a strong pick for anyone who enjoys tuning and experimenting with their fidget.
If you want a simple, single-feel slider, this may be more complexity than you need. But if you are looking for a Nayici EDC fidget that rewards tinkering and offers a genuinely different feel from typical mechanical sliders, the Core Wave-03 is worth considering.
