Staleks Pro - Double-Ended Liner Brush 7mm / 10mm

Staleks Pro Double-Ended Liner Brush Expert 7 mm / 10 mm: the essential double-ended brush for ultra-fine lines and a flawless French

In the world of professional nail services, you already know it: the difference between a “nice” set and a truly premium finish is all in the details. And for details that look clean, consistent, and elegant, you need a tool that follows your hand with absolute precision. The Staleks Pro – Double-Ended Liner Brush Expert 7 mm / 10 mm was created for exactly that. Its double-ended design is ideal for professionals who want to save time, streamline their workstation, and keep total control of every stroke—whether you are creating a delicate French, an ultra-fine line, or a crisp geometric pattern.

With two complementary liner tips, 7 mm and 10 mm, this brush naturally adapts to your technique: the shorter tip for demanding areas, micro-details, and refinements, and the longer tip for smooth, continuous strokes and designs that require beautiful regularity. It is a true ally for nail technicians, nail artists, and beauticians, but also for at-home nail lovers who want a cleaner, sharper, more professional-looking result.

Why choose a double-ended brush for nail art and French work?

A double-ended brush is more than a simple “two-in-one”. It is a smarter way to work. In services, you often need to switch between a shorter and a longer liner to get a perfectly balanced finish: a controlled curve, a razor-thin straight line, a crisp corner, or a clean outline near the cuticle area. The Staleks Pro Expert lets you move from one stroke to another without changing tools, helping you keep pace and precision—especially when you are recreating the same design across multiple nails.

The promise is clear: absolute precision from the first millimetre to the last. Lines stay clean and even, without that “wobbly” look or unwanted thickness changes. The bristle shape also supports a flawless French, making it easier to reproduce the same smile line on every nail—essential for a harmonious look across all ten fingers.

Detailed usage guide: how to get the perfect stroke with a liner

Precision does not come from the brush alone—it also comes from how you load it and position it. With the Staleks Pro Double-Ended Liner Brush Expert, the goal is to work light, avoid overloading, and keep the tip sharp for consistent lines.

Step 1: prep the nail for clean work

1. Follow your usual prep: shaping, cuticle work, dust removal.
2. Apply your base and colour (according to your protocol) and cure/dry as required.
3. Make sure the surface is clean and ready: an overly slick or overloaded layer can reduce line crispness.

Step 2: choose the right tip (7 mm or 10 mm)

1. Use the 7 mm tip for details close to the cuticle area, mini motifs, and refinements.
2. Use the 10 mm tip for long strokes, continuous curves, separation lines, and more fluid designs.
3. Switch easily depending on the nail: the double-ended format helps you stay focused on the stroke.

Step 3: load the brush like a pro

1. Pick up a small amount of product (gel paint, highly pigmented gel colour, nail art gel).
2. Wipe off excess on a palette to keep a fine, well-defined tip.
3. Lightly roll the brush between your fingers to re-form the point and align the bristles.

Step 4: create a delicate, consistent French

1. Stabilise your hand: rest your wrist, anchor a finger to reduce shaking.
2. Place two guide points to map the curve of the smile line.
3. With a light touch, connect in one fluid stroke while keeping a soft angle—the tip should glide, not scrape.
4. Refine if needed with the 7 mm tip to sharpen the French corners.
5. Cure/dry, then finish your service (top coat, finishing gel, etc.).

Step 5: create fine lines and geometric designs

1. Use very little product: this is the secret to a crisp, thin line.
2. For a straight line, place the tip and pull in one continuous motion—avoid repeated passes.
3. For angles, pause at the corner, change direction, and continue without pressure.
4. For a graphic look, keep the same stroke thickness on every nail.

Pro tips for an even cleaner result

• Anchor your movement: lightly rest your little finger on the client’s hand or your support to stabilise the line.
• Choose finesse: overloading thickens the stroke and increases the risk of smudging.
• Work in layers: for complex motifs, build the structure first, cure if needed, then add micro-details.
• Use the 7/10 mm duo: 10 mm for flow, 7 mm for surgical precision.
• Consistency across 10 nails: for a high-end service, keep curves and line thickness uniform.

Care and durability: how to preserve the tip and bristle flexibility

The bristles are designed to be deformation-resistant, but proper care remains essential to keep the tip precise. A well-maintained liner means cleaner strokes, better control, and a longer lifespan.

• Clean immediately after use: do not let product set in the bristles, especially when working with gels.
• Wipe gently: avoid twisting the tip or scrubbing aggressively, which can misalign the bristles.
• Re-form the point: after cleaning, align the bristles and recreate a fine tip before storing.
• Store properly: protect both tips in a pouch or case to prevent crushing in a drawer.
• Professional hygiene: keep a clean workstation protocol for an impeccable and safe service.

Aluminium handle: lightweight, sturdy, and comfortable to use

The aluminium handle is a real advantage in the salon and at home. It is lightweight, making your movement more precise while reducing strain on the hand. It is also sturdy, resisting everyday knocks. This combination delivers a more stable sense of control, especially for meticulous work where every millimetre matters. And during back-to-back appointments, that comfort becomes a quiet luxury: you keep your precision without exhausting your hand.
