Sandwich Dual Forms – Almond & Coffin Shapes for perfect nails shapes!

Create salon-sharp extensions faster and easier with our new Sandwich Dual Forms, innovative designed with a top + bottom sandwich-style structure to help evenly shape your gel or acrylic enhancements.

These advanced dual forms feature a curved, supportive mould that keeps product tight, smooth and consistent from cuticle to free edge, helping you achieve flawless almond shaped nails and coffin shaped nails with less filing and fewer bubbles.

Whether you work with builder gel, acrylic, Polygel, or hard gel, these forms deliver consistent thickness and an ideal C-curve every time.

Key Features
  • Sandwich-Style Mould: Two-layer shaping design helps control product and achieve an even, professional result.

  • Perfect Almond or Coffin Shape: Pre-curved form gives a crisp salon finish with minimal refining.

  • 15 Sizes – 240 Pieces: Full size range suitable for all nail types.

  • Reusable & Strong: Made from high-quality, clear ABS for excellent visibility and easy removal.

  • Beginner-Friendly: Ideal for nail techs learning extensions or wanting faster, cleaner application.

How to Use
  1. Prep the natural nail and apply base coat if doing polygel or gel enhancement.

  2. Select a Sandwich Dual Form slightly larger than the natural nail.

  3. Apply your product inside the form, keep edges thin to reduce overflow.

  4. Press the form onto the nail and smooth the sides + underside.

  5. Cure fully for 60 seconds.

  6. Pinch the tabs and gently pop off the form.

  7. File lightly to refine the shape if needed.

Great product

Im only a DIYer so thought id give these a go..I think the builder in a bottle ( which is what I tried using ) just wasnt thick enough and user error I made a mess ..these were of great quality but I think for me to get the best out of them Id use Polygel or hard gel..other than that very good.

This is the first time I have ever used polygel and this kit game me everything I needed

This is the first time I have ever used polygel and this kit game me everything I needed. I had been using dip powder with the gel method previously and wanted to give polygel a try.
I used the pink that came with the kit and after a quick learning curve, I felt quite comfortable using the product and I am very happy with the outcome!

⭐️⭐️⭐️⭐️⭐️ – Fun little challenge!

I grabbed these Sandwich Nail Dual Forms after seeing them on TikTok and thought they’d be super easy. Turns out I’ve got a LOT of learning to do. But I love the concept, and I can totally see how amazing they’ll be once I’ve put in the hours of practice. Excited to keep trying and get the hang of it!

Brilliant for beginner, strong and durable

I love the Poly Gel I use it with tips because I am super rough and knock my nails about a lot and tips provide that extra bit of strength. The Poly Gel is fantastic there is none of this trying to get the perfect arch on your nail it the frame work does it for you! This product is brilliant for beginners!!!!!
