U-Shinein Nail Extension Dual Forms 120PCS Clear Reusable Acrylic Molds — 12 Sizes Oval & Square for Builder Gel/Polygel Quick Cur

U-Shinein Nail Extension Dual Forms are a 120-piece reusable acrylic nail form set in 12 sizes that let you sculpt oval and square poly/acrylic extensions quickly and cleanly.

Whether you’re a salon pro or a DIY enthusiast, these transparent, glossy nail molds give precise control over length and shape without messy paper forms or sticky tabs. The kit includes 120 clear acrylic forms organized into a compact case; the forms work with builder gel, polygel and acrylic systems and release easily after curing under a UV/LED lamp. Built for repeat use, each form features printed guidelines to help you create consistent extensions, French tips and customized designs.

How do these forms speed up my manicure routine?

These dual forms eliminate trimming, filing and fitting steps that slow down freehand builds. Choose a size, apply product inside the concave mold, place over your nail plate and cure—no adhesive needed. The rigid acrylic keeps shape during application, so you spend less time correcting contours and more time finishing color or nail art.

• Pre-shaped concave molds reduce shaping time and sanding.
• Clear material lets you check gel thickness and placement before curing.
• Works with UV/LED cure in about 30 seconds for quick sets.
• Reusable construction avoids constant form replacement.

Which sizes and shapes are included, and how do I pick the right one?

The set contains 120 pieces across 12 sizes, arranged in nine small grids inside the storage case for easy selection. Sizes range to accommodate narrow and wide nail plates, and each form supports both oval and square tip profiles so you can switch styles without changing tools. Try the closest fit and sand or fill minimally for a perfect edge.

• 12 distinct sizes cover most adult finger dimensions.
• Transparent forms let you align product with natural nail tips accurately.
• Marked guidelines assist length and apex placement for consistent results.
• Organized storage keeps each size visible and accessible.

What nail systems work with these acrylic forms?

The forms are compatible with builder gels, polygel and acrylic—any viscous extension product designed to be cured or dried inside a mold. They were designed to resist deformation under pressure and peel away cleanly once the product is cured, so your finished extension is smooth and glossy. Avoid direct skin contact with uncured product and follow manufacturer safety instructions for all materials used.

• Compatible with polygel, builder gel and acrylic overlays.
• Use UV/LED lamp for gel/polygel curing, approximately 30 seconds as a guideline.
• Forms release after the product hardens—no glue required.
• Works for creating clear, French or colored extensions.

How do I clean and store the forms for long life?

Because the forms are made from hard acrylic, they withstand multiple uses when cleaned properly. Remove sticky residue right after use, wipe with a non-acetone cleaner or gentle alcohol, and return to the case’s grid to avoid warping. Proper handling preserves the printed markers and keeps edges crisp for accurate builds every time.

• Wipe off uncured product promptly with alcohol or recommended cleaner.
• Avoid acetone soaking to prevent dulling printed guidelines.
• Store flat in the included case to maintain shape and organization.
• Keep away from children and follow all safety instructions on products used.

Who is this for: The U-Shinein Nail Extension Dual Forms set suits professional nail technicians, salon owners and home users who want a faster, cleaner way to create acrylic or polygel extensions. It’s particularly helpful for technicians aiming for consistent lengths and shapes across clients, and for hobbyists who prefer reusable, easy-to-handle forms that cut down on filing and reshape time.
