gelike ec Sandwich Dual Forms for Polygel — 240pcs (15 Sizes) Reusable Square Forms with C-Curve & Etched Guides

Gelike EC Sandwich Dual Forms are reusable square dual molds designed to create salon-quality polygel, builder gel, and acrylic extensions with precise alignment guides and a reliable C-curve.

These dual forms come in a 240-piece kit spanning 15 sizes (0–14) to fit a wide range of nail shapes. Made from high-clarity, high-flexibility PMMA, they are engineered to provide consistent light transmission, a rigid-but-flexible frame that holds shape during curing, and laser-etched trimming guides so you can sculpt short, medium, or long extensions quickly and evenly. The sandwich design eliminates common issues like side overflow and separation while producing a smooth underside that needs minimal extra filing.

How do these dual forms make DIY manicures faster and more consistent?

The etched alignment guides remove guesswork, so you spend less time measuring and more time applying product. The sandwich construction holds gel or acrylic in place during curing, reducing spills and refits. Because the underside cures smooth and even, you’ll also cut down on filing time after removal.

• Laser-etched guides for instant length consistency
• Sandwich form prevents side overflow and air gaps
• Crystal-clear PMMA allows complete light cure every time
• Reusable for 20+ uses, speeding up fills and repairs

Which materials work with Gelike EC Sandwich Dual Forms?

These dual forms are compatible with polygel, builder gel, and acrylic systems thanks to the sandwich mold shape that bypasses adhesion and lifting problems common with single-material forms. The PMMA shell resists warping and maintains consistent shape across products for repeatable results.

• Polygel: perfect for shaping and quick curing
• Builder gel: holds structure without buckling
• Acrylic: supports proper flow and even underside finish
• Works for repairs and full-set extensions alike

Will these forms deliver the salon C-curve and reduce filing?

The combination of a feather-thin flexible base and straight-sided frame produces a salon-style C-curve with clean edges. The underside cures smooth and thin, minimizing the need for aggressive filing or reshaping after release. Proper prep—trimming the natural free edge short—ensures the extension sits flush and strong.

• C-curve arch with straight sides for structural strength
• Feather-thin base creates a seamless underside
• Minimal post-cure filing when applied correctly
• Guides help maintain symmetrical curves across all nails
