Stunning 3D multi-chrome nail extensions with magnetic polygon effects—salon-quality results in minutes
Transform your nails into light-reactive art with six mesmerizing shades that shift color with every movement. Our complete poly extension nail kit delivers durable, professional-length manicures without the salon appointment.
From salon regular to certified nail architect
Because your manicure budget deserves a serious upgrade.
The Burden of Beauty
Salon bills pile up as fast as your gel chips. You're tired of rushed appointments and limited pink-and-red palettes. The dream of nail extensions that look custom—not cookie-cutter—feels out of reach.
Light in Your Hands
Enter a chromatic universe where six multi-chrome gels react to a simple magnet, creating patterns that move with the light. No UV lamp stress, no sticky residue—just quick-building, flexible nail care innovation that puts the power of a pro salon on your vanity.
Three reasons this kit outperforms your usual gel set
Every element designed for the at-home esthete who demands salon-grade results.
6-Shade Multi-Chrome Palette
Each 15ml tube is a different personality: from silver shimmer to twilight purple, every shade reacts to the magnet, creating a 3D polygon effect no flat polish can match.
Complete Professional Toolkit
Not just gels. This black gift box comes with a dual-ended brush, nail forms, slip solution, base and top coat, and the magnetic wand—all you need for a flawless manicure.
Quick-Building Formula
The advanced poly gel self-levels for a smooth foundation in minutes, cures under UV/LED, and stays chip-free for weeks—no nail forms dragging or uneven ridges.
Your first poly extension in minutes
Follow these steps for a flawless, magnetic finish.
- 01
Prep
Push back cuticles, lightly buff natural nails, and cleanse with alcohol. Place a nail form snugly under the free edge.
- 02
Base
Apply a thin layer of base coat and cure under UV/LED lamp for 60 seconds.
- 03
Build
Dip the dual‑ended brush in slip solution, pick up a bead of gel, and pat/press onto the nail form to shape the extension. Keep it smooth and gradual.
- 04
Cure
Cure the shaped gel under the lamp for 90–120 seconds until hard. Remove the nail form and check the arch.
- 05
Magnet
Apply a second thin layer of gel (uncured), hover the magnetic wand 2–3mm above the nail for 10–15 seconds until the desired polygon effect appears, then cure.
- 06
Finish
Seal with top coat, cure one final time, and wipe off the inhibition layer with alcohol. Voilà!

Make your magnetic extensions last
Simple habits for a long‑lasting high‑gloss finish.
- Wear glovesProtect your extensions from harsh cleaners and prolonged water exposure.
- Oil cuticles dailyA drop of cuticle oil keeps the gel junction flexible and prevents lifting.
- Avoid pryingNever use your nails as tools — opening cans or peeling labels can stress the extension.
- Maintain every 2‑3 weeksA quick infill near the cuticle prolongs the set without starting over.
- No acetone soaking dailyRemove only with full acetone soak; avoid short dips that weaken the bond.

Takes a little practice to get the magnet angle right, but once you do, the depth is unreal. Worth the effort.
The magnet tool is powerful—creates a sharp polygon line instantly. Just wish the brush was a tiny bit finer for detailed work.
The emerald mystique under sunlight is jaw-dropping. I keep catching myself staring at my own hands.
