Makartt Sandwich Dual Nail Forms for Builder & Poly Gel Extensions — 280 PCS, 14 Sizes, Clear Reusable

Makartt Sandwich Dual Nail Forms are a two-piece reusable top-and-bottom mold system that helps you build cleaner, more controlled long coffin gel and poly gel extensions with less filing and mess.

Whether you work in a busy salon or enjoy salon-standard manicures at home, these clear sandwich-style forms are engineered to hold builder gel and poly gel precisely where you place it. The interlocking top and bottom pieces form a contained cavity that supports a smooth underside and creates a natural C-curve while built-in guide lines help you match lengths across every finger. Included are 280 pieces across 14 sizes so you can fit different nail beds and design longer shapes reliably.

How do these dual forms reduce filing and reshaping after curing?

The two-part sandwich locks gel between a shaped top and a supportive bottom, preventing the gel from flowing outward during curing. This containment produces a pre-formed arch and cleaner sidewalls that require far less post-curing shaping. Less excess material means shorter sessions and a finer finish straight from the lamp.

• Top-and-bottom interlock keeps gel centered and controlled.
• Pre-formed C-curve minimizes filing time for undersides.
• Clear material lets you inspect gel placement before curing.
• Removable tab simplifies mold release without damaging the nail.

Which nail systems work best with Makartt Sandwich Dual Forms?

These clear PMMA molds are compatible with builder gels, poly nail gels, and traditional acrylic systems, making them a versatile tool for a range of extension techniques. Because the forms hold the product in a fixed shape during curing, they suit both slow-build sculpting and quick encapsulation workflows. Note: for secure placement of the bottle mold, a peel-off base coat is recommended.

• Built for builder gel and poly gel applications.
• Works with acrylic when used carefully for shaping.
• Reusable material stands up to repeated cleaning and use.
• Guide lines help keep different systems consistent in length.

How do I choose the right size and shape from the 14-size set?

The kit includes 14 distinct widths to accommodate varied nail beds and extension lengths. Start by trying sizes that closely match your natural nail width, then use the built-in scale lines to set the desired length for each finger. Keep a few adjacent sizes on hand to tailor the perfect tapered coffin or almond silhouette for each client or hand.

• 14 sizes provide close fits for most nail shapes and widths.
• Scale lines make length matching fast and repeatable.
• Use neighboring sizes for narrow or wide nails on the same hand.
• Clear molds let you view the underside and adjust before curing.

How do I care for and reuse the sandwich molds effectively?

After each use, remove cured product gently and wash the forms with non-abrasive soap or gentle cleaner to avoid scratches. Store flat or in a protective box to retain shape and transparency; avoid high heat that could warp the PMMA. With proper care, these forms deliver repeated clean uses and reduce waste compared with single-use paper forms.

• Clean with mild soap and water; avoid harsh solvents.
• Dry thoroughly and store flat to maintain shape.
• Inspect for residue or scratches before reuse.
• Avoid prolonged exposure to high heat or direct sunlight.
