Brunson Express Dual Sandwich Nail Extension Tips – Oval Shape Sandwich Dual Form (240pcs)
If you’ve ever spent 10 minutes buffing and sealing a single nail extension, you already know the frustration. You do all that work on the application — and then comes the finishing grind. The Brunson Sandwich nail extension tips – oval shape is built to change exactly that.
This is the world’s first sandwich-style nail form that uses both a top mold and a bottom mold, clamping around your gel during curing so that every surface of the extension is shaped at once. When you pop the mold off, the nail is finished. No filing the top, no sealing layer, no leftover glue on the finger core. Just clean, smooth, ready-to-decorate nails.

What Makes the Sandwich System Different?
Most nail forms only support the nail from underneath. They shape the underside of the extension, but the top and sides are left to whatever your brush and your filing skills can produce. That’s why finishing takes so long — you’re essentially sculpting freehand after the fact.
The Brunson dual sandwich form changes the whole equation. Both a top mold and a bottom mold clamp around the gel during curing, shaping all surfaces simultaneously. The result is an extension that comes out of the mold already smooth — top, bottom, and sides — with no rough patches and no overflow residue to clean up.
The only step that still requires a quick touch-up is the sidewalls, where a light pass of a file finishes the edge. Everything else is done the moment you demold.
About the Sandwich Nail Tips W557 Shape: Oval
The W557 comes in an oval shape — one of the most timeless and universally flattering nail shapes available. It’s the kind of shape that works beautifully for everyone: elegant enough for special occasions, wearable enough for everyday life, and classic enough to never go out of style.
Oval extensions follow the natural curve of the fingertip with gently rounded sides and a softly curved tip, creating a smooth, continuous silhouette that feels effortlessly polished. The shape visually elongates the fingers and makes hands look slender and graceful, while remaining comfortable for daily wear. If you’re working with clients who want something sophisticated and refined, or if you’re looking for a shape that flatters every hand, the W557 oval is the perfect choice.
Key Features of Brunson Sandwich Nail Extension Tips – Oval Shape
1. Dual Mold — Top + Bottom Clamping
The Brunson Sandwich nail extension tip – oval shape comes with two components that work together: the bottom mold sits under the gel and supports the extension, while the top mold presses down from above. Together they hold the gel in precise position throughout the entire UV/LED curing cycle, shaping all surfaces at once. No guesswork, no free-forming — the mold does the work.
2. Demolding Is (Almost) the Finished Product
When you remove the mold, the top and bottom surfaces of the extension are smooth and clean. The finger core has no glue accumulation. You won’t need to apply a sealing layer, buff the top surface, or spend time cleaning residue off the skin. The one finishing step that remains is a light file of the sidewalls — and that’s it.
For a full set of 10 extensions, this alone can save 30–60 minutes per client compared to traditional methods.
3. Ultra-Thin Wing Design — 0.2 mm Trailing Edge
Traditional nail forms have trailing edges between 0.5 mm and 1.0 mm thick, which creates a noticeable step between the natural nail and the extension. The Brunson form comes in at just 0.2 mm — thin enough to follow the natural nail’s curvature closely and produce a seamless, natural-looking result.
The wings on both sides of the mold also do three important jobs:
- They hold the top mold at the correct height above the nail
- They prevent excessive downward pressure that would make the extension too thin
- They contain the gel and prevent overflow during application
4. Easy to Fit, Easy to Remove
The bottom mold snaps flush against the natural nail, and the top mold clips securely over it. Sizes run from 0 (widest at 13.59 mm) to 14 (narrowest at 6.35 mm), so you can find a proper fit for every finger. After curing, the mold flexes off cleanly — no sticking, no pulling.
5. Works with All Major Gel Types
The sealed dual-mold environment is compatible with:
- Polygel (acrygel) — the world’s most widely used nail extension gel
- Builder gel — including BIAB-style products
- Sculpting gel — hard gel nail extension products
- Acrylic gel — hybrid products for maximum strength
The clamping design also helps prevent the gel overflow that’s common with polygel and builder gel on open-ended traditional forms.

How to Use the Brunson Dual Sandwich System
Whether you’re a professional nail tech or doing your own nails at home, the process is straightforward.
- Select your size — match the top mold to each natural nail without overlapping the skin.
- Prep the natural nail — clean, dehydrate, buff lightly, and apply primer or base coat.
- Apply gel to the bottom mold — don’t overfill; the sandwich clamp spreads it evenly.
- Snap the bottom mold onto the fingertip, flush with the natural nail plate.
- Close the top mold — the wings lock it at the right height and seal the edges.
- Cure under UV or LED lamp for the time your gel product recommends.
- Demold — flex off the top mold, then the bottom. Lightly file the sidewalls. Done.
- Decorate (optional) — apply gel polish, nail art, chrome powder, or top coat directly on the finished surface.
Who Is This For?
- Professional Nail Technicians : The dual sandwich system is a genuine time-saver for busy salons. Cutting out most of the post-cure finishing means you can serve more clients per day without rushing the application. The consistent mold results also reduce the quality variation that comes with hand-filing — every extension looks great, regardless of who applied it.
- Beginners and Home Users : If you’re learning nail extensions at home, traditional methods demand a lot of practice before the filing and shaping steps look good. With the Brunson system, the mold handles all the shaping. You focus on gel application and placement — and the result still looks professional.
- Nail Educators and Students: Training programmes can use the dual sandwich form to teach gel application independently from filing technique. Students can build confidence with the gel process before adding shaping skills to the mix.
