ZIMOOM Sandwich Dual-Form Nail Kit 240pcs — Clear Long Coffin, 15 Sizes Reusable Plastic Forms for Quick Polygel Extensions

ZIMOOM 240Pcs Sandwich Nails Dual Forms is a complete clear dual-form kit that lets you create consistent, salon-quality nail extensions quickly using a simple fill-press-cure-peel method.

Whether you’re a busy stylist or a home nail enthusiast, this ZM-W555-Long Coffin kit combines an innovative sandwich design with high-grade reusable plastic and 15 sizes to fit most nail shapes. The kit’s interlocking top and bottom forms lock together to keep builder products contained and prevent deformation during curing, making it easier to achieve long, smooth coffin-shaped extensions without wasting product.

How does the sandwich dual-form design improve extension results?

The dual-form system uses matching top and bottom pieces that click together around the nail, creating a secure cavity for polygel or builder gel. This keeps the extension’s shape stable while curing and reduces air pockets and spills, resulting in cleaner, smoother finishes.

• Upper and lower molds interlock for stable, uniform shapes
• Clear plastic allows visibility to check product placement
• Prevents bending or warping during lamp curing
• Easy demold for consistent surface texture

Can beginners use this kit to do a full set of nails?

Yes — the kit is designed with simplicity in mind. Follow the four-step workflow (fill, press, cure, peel off) and even novices can complete a full set in about ten minutes once they’ve practiced the technique a couple of times.

• Numbered sizes speed up selection for each finger
• Clear instructions and visual guidance reduce mistakes
• Reusable pieces let you practice without extra cost
• Compatible with polygel, builder gel, and similar systems

What sizes and quantities are included, and will they fit my clients?

The kit contains 240 pieces across 15 sizes, including five sizes made specifically for thumbs to accommodate a wide variety of hand shapes. The broad size range and clear numbering make it simple to match each nail for a snug, natural-fitting extension.

• 15 distinct sizes to cover petite to large nail beds
• Five thumb-specific sizes for better fit on thumbs
• 240 total forms to support multiple full sets and practice
• Numbered molds speed up salon workflow

How durable and reusable are these clear plastic forms?
