 The Disaster of Traditional Nail Forms/Dual Forms

Let's start with the familiar pain points. Whether it's paper nail forms or the common plastic dual forms, most girls have encountered these pitfalls:

Paper nail forms:

If the placement is slightly off, the entire extension will be crooked.

Achieving a perfectly rounded and symmetrical C-curve is difficult, relying entirely on feel.

Gel/acrylic tends to overflow from the edges, requiring extensive buffing and shaping after curing.

Regular dual forms:

There's only one top mold, and the angle at which it's applied to the natural nail requires skill.

Overflowing glue, uneven base, inaccurate application, slippage, misalignment—ten fingers, ten different shapes.

The base is open, allowing buffing dust to seep into the natural nail folds.

Therefore, many girls who aren't skilled with nail forms and dual forms simply give up on extensions—believing only nail technicians can handle them.

 

Sandwich Dual Nail Forms make this process "controllable."

I. What are Sandwich Dual Nail Forms?

Simply put:

It's a sandwich-structure dual-form system with "top and bottom molds clamped together," transforming nail extensions from a "craft" to a "structural engineering" process.

Core Structure: Top Mold + Bottom Mold (Top Mold + Bottom Mold) pressed together

Top Mold: Determines the curvature, length, and shape of the surface.

Bottom Mold: Adheres to the natural nail, seals the base, and provides structural support.

The two are pressed together in a "press-fit" manner, making the extension resemble a "sandwiched" shape.

Direct results of this structure:

Cleaner C-curve: The mold itself is designed with a standard C-curve, leveraging "engineering precision," not your craftsmanship.

More Consistent Symmetry: The top and bottom molds are locked in place, fixing the left and right/front and back, making it less prone to drifting than ordinary nail forms.

Less Glue Overflow: Less glue overflow at the edges compared to paper forms/traditional nail forms, significantly reducing the need for later adjustments.

Safer Sanding: The bottom film seals the bottom, preventing debris and dust from the sanding head from sticking.

III. Comparison with Traditional Nail Forms & Dual Forms

1. Structural Comparison

Item | Traditional Nail Forms (Paper Base) | Ordinary Dual Forms | Sandwich Dual Nail Forms

Structure | Single-layer paper base, surrounding the fingertip | Single top mold | Top + Bottom | Sandwich locking

Stability | Easy to shift, easy to lift | Easy to slide, fit relies on feel | Top and bottom molds locked, less prone to shifting

Bottom Protection | Bottom completely open | Partially open | Bottom film seals the bottom, preventing dust from entering

C-shaped Curve | Relies on manual pinching | Mold exists, but easy to misalign | Mold geometry + top and bottom locking

Glue Overflow | Easily overflows at the edges | Also easy to overflow if not skilled | Controllable clamping space, less glue overflow

Sanding Workload | Relatively large | Medium | Significantly reduced

 

2. Significance for Different Groups

For beginners: You no longer need to learn how to apply paper bases or how to control the angle of dual forms.

Once you understand how the top and bottom layers work together, the fundamentals of nail extensions can be systematically mastered.

For experienced technicians: With practice, the time spent on shaping and polishing will be significantly reduced.

The mold itself has already handled most of the shaping.

240 pieces per box (8 pieces/compartment × 30 compartments), perfectly meeting the standard for high-frequency salon use

V. Compatible with Multiple Systems: More Than Just a Set of Gel Nail Forms

This Sandwich Dual Nail Forms set It's not limited to a single system, but designed as a **system-wide universal**:

It can be used as gel nail forms

It can also be used as nail forms for acrylic nails

Compatible with:

Hard gel

Extension gel / Poly gel

Acrylic system

In other words, you don't need to buy separate sets of nail forms for gel and acrylic;

One set of sandwich dual nail forms basically covers most of your extension projects.

VI. Key Selling Points: Why do professional nail technicians choose it?

C-curve Engineering Design: The mold geometry directly determines the apex height and lateral balance, reducing issues like "collapsed waist" or "one side higher than the other."

High Transparency Material:

You can see bubbles and material thickness during curing

You can check if the gel/acrylic is evenly spread

Quick Demolding, Cleaner Edges: The inner wall is smoothly polished; after curing, a gentle tap unlocks the top/bottom mold,

resulting in smoother extension edges, which essentially reduces the amount of finish filing.

Durable and Reusable: Made of sturdy material, and with proper sterilization procedures, it can be used multiple times.

For salons, this makes it a more cost-effective one-time investment.

Professional Packaging:
8 sheets per compartment × 30 compartments = 240 sheets/box, clearly categorized for efficient use.

VII. How to use Sandwich Dual Nail Forms? Step by Step

The following can be used directly as a salon SOP or a tutorial to show clients 👇

Applicable to: gel nail forms / nail forms for acrylic nails

Step 1 – Preparation

Prepare the basic nail surface:

Remove cuticles and push back the cuticles

Lightly buff the nail surface to remove oil

Use a dehydrating agent and primer if necessary

Choose the appropriate Top & Bottom sizes:

Ensure the mold sides just cover the sidewalls, without pressing on the nail or leaving obvious gaps.

Step 2 – Install the Bottom Mold

Attach the Bottom Mold to the under/around of your natural nail,

feel how well it adheres to the nail surface and sidewalls.

Confirm a good "sealing" at the base – this step is crucial:

It determines whether subsequent powder can penetrate the nail tip

It also enhances the overall structural stability

Once the base coat is in place, you'll feel that the extension is "supported," rather than suspended on the paper base.

Step 3 – Laying Material Inside the Top Mold

Place an appropriate amount of extension material inside the Top Mold:

Hard gel / extension gel / acrylic are all acceptable.

Using the C-curve naturally formed on the inner wall of the mold,

spread the material evenly, paying attention to the transition between the leading edge and the sidewalls.

 

Tip:

Slightly less than your desired final thickness,

The subsequent pressing will allow the material to naturally flatten and fill the space.

Step 4 – Top & Bottom Pressing Sandwich Core

Place the material-filled Top Mold from above to the fingertip,

aligning it with the Bottom Mold.

Gently press to lock the press-fit between the top and bottom molds.

Check from multiple angles:

Is the C-curve symmetrical?

Is the extension length uniform?

Are both sides flush with the natural nail sidewalls?

Because the top and bottom molds are structurally fixed,

compared to regular dual forms, you don't need to constantly worry about it slipping or shifting.

Step 5 – Curing & Demolding

Cure under the lamp according to the normal curing time for the material system.

After curing, gently remove the Top Mold first, then the Bottom Mold.

Check:

Are the edges smooth?

The areas needing adjustment are usually only very minor details.

Because the inner wall is polished smoothly, the feel of the Fast demold will be very noticeable—the mold gently "pops open," and the extended nail edge is already very clean.

Step 6 – Sanding, Cleaning & Coloring

Simple shape adjustments (square, oval, coffin shape, etc.)

Sand any uneven areas on the surface.

Wipe away dust and apply a top coat/color/artistic design.

The base coat already acts as a "bottom barrier" during the curing stage, so dust generated during sanding at this point will not penetrate the gaps inside the nail tip, greatly improving comfort and hygiene.

VIII. What changes are there for beginners and experienced nail technicians respectively?

For girls unfamiliar with nail forms/dual forms:

No more figuring out how to cut and apply nail templates.

No more calculating the depth and angle of dual forms.

The geometric molds and clamping mechanism help you structurally solve the "most difficult part."

The operation is more like "assembling building blocks" than "sculpting nails."

You only need to focus on choosing the right size and controlling the amount of material to achieve a stable and replicable extension effect.

For professional nail technicians/advanced users:

Most of the time is shifted from buffing and shaping to design, color matching, and artistic expression.

Higher nail shape consistency, making it easier to standardize details on all ten nails.

Compatible with multiple systems (gel + acrylic), eliminating the need to frequently switch between different nail forms tools.

IX. Conclusion: Sandwich Dual Nail Forms are more than just "another set of dual forms."

If you had to summarize this product in one sentence:

It integrates the advantages of nail forms and dual forms,

and then uses "engineering" and a "sandwich structure" to perform a system-level upgrade.

For beginners: Makes nail extensions controllable, learnable, and replicable.

For experienced nail technicians: Makes time more valuable, shifting focus from "nail shaping" to "creating masterpieces."

For clients: Cleaner nail shapes, less dust intrusion, and a more comfortable experience.
