2-in-1 Straight & Tapered Square Dual Nail Forms — 112 PCS
Two Square Shapes. Pre-Balanced Apex. Zero-Fuss Application.
Create crisp, salon-grade square extensions in minutes with significantly less shaping and filing. Each double-end reusable form combines a classic straight square on one end and a tapered square on the other, which gently narrows toward the free edge for a slimming look. Two in-demand square styles in a single box.
- 2 Shapes in 1 Form: Switch between bold straight square and slimming tapered square without buying separate sets.
- 14 Tailored Sizes (112 PCS): Complete sidewall-to-sidewall fit eliminates side gaps and cuticle lifting.
- Pre-Built Apex & C-Curve: Built-in structural curve supports length and cuts filing time by over 50%.
- Non-Stick Clean Release: Flexible premium material pops cleanly off cured gel with a gentle flex.

How to Use for Flawless Square Extensions
- Prep: Cleanse, push cuticles back, gently buff the nail plate, and apply dehydrator and primer.
- Fit: Choose a form that covers from sidewall to sidewall without pressing flat.
- Apply: Brush builder gel or smooth polygel inside the straight square or tapered square end, keeping the cuticle edge slightly thinner.
- Place & Flash Cure: Position at a 45-degree angle near the cuticle and gently lay down. Flash cure for 10–15 seconds to freeze position, clean the underside, then full cure (60s LED / 120s UV).
- Release: Gently squeeze the side wings—the form pops off with zero residue.
- Finish: Lightly shape the free edge, apply gel top coat, and cure.
