Makartt Sandwich Dual Nail Forms 280 PCS, 14 Sizes — Reusable Clear Long Almond Molds

Makartt Sandwich Dual Nail Forms are a two-piece top-and-bottom molding system that holds builder or poly gel in place to create cleaner, long almond gel extensions with less reshaping.

These reusable clear PMMA forms come in 280 pieces across 14 sizes and are designed for the sandwich technique: gel is applied between an upper and lower mold to control overflow, support the underside, and guide the outer surface. The visible guidelines and pre-shaped long almond silhouette help deliver consistent lengths and profiles whether you’re working in a salon or doing nails at home.

How do these dual forms make gel extensions neater?

The matched top and bottom molds enclose the builder or poly gel so it can’t spread unpredictably during application and curing. The bottom piece supports the underside of the extension while the top shapes the visible curve, reducing the need for heavy filing after the lamp.

• Sandwich design contains gel to the intended shape and thickness
• Bottom mold prevents sagging and helps smooth the understructure
• Top mold guides consistent apex and outer curve
• Clear material lets you check gel placement before curing

Which nail products and techniques work best with these forms?

They’re built for builder gel and poly nail gel but also work for overlays, nail reinforcement, and custom extensions where a supported underside is helpful. For very short natural nails, use just the top mold as a single dual form or create a small natural free edge to seat the bottom mold.

• Ideal for builder gel and poly gel extension methods
• Suitable for overlays, sculpted tips, and reinforced natural nails
• Top-only option for extremely short nails or quick applications
• Reusable after cleaning for multiple applications

How do I choose sizes and control length consistently?

The set includes 14 sizes with visible guide lines printed on each clear form so you can pick the size that best matches the nail bed and set identical extension lengths across fingers. The long almond pre-shape reduces time spent sculpting and helps produce a uniform silhouette from nail to nail.

• 14 sizes cover a wide range of natural nail widths and shapes
• Guide lines mark length and center alignment for repeatable results
• Pre-shaped long almond profile speeds sculpting and filing
• Transparent forms make fit-checking and gel placement easier

What maintenance and reuse tips help get the best results?

Clean cured residue from the forms promptly and avoid abrasive solvents that could cloud the PMMA. Store forms flat and away from heat to keep their shape; inspect regularly for nicks that can transfer texture to the cured gel.

• Wipe forms with non-abrasive cleaner immediately after use
• Avoid high heat and prolonged UV exposure when storing
• Replace any forms with deep scratches to prevent imperfections
• Use a small natural free edge to help the bottom mold sit securely

Who is this for? Nail technicians, students, and home DIYers who want a tidier, more repeatable long almond extension without constant heavy filing will benefit most from these forms. If you use builder gel or poly gel and prefer a controlled, no-mess workflow that supports the underside and outer curve at once, the Makartt Sandwich Dual Nail Forms provide a reusable, guideline-marked solution suited to both practice and professional use.
