Micro-liner brush draws continuous hair-thin French curves with zero bristle split.
A 7 mm length size 00 detail instrument engineered with high-memory synthetic nylon filaments, clamped inside a solvent-resistant copper ferrule that survives repeated acetone and cleanser washings.

Mass-market brushes use water-soluble animal glue inside an unsealed aluminum tube. When alcohol or acetone penetrates the ferrule, the glue dissolves, releasing hairs and bowing the central core outward.
Our 7 mm Micro-Liner embeds every filament in a high-grade vulcanized epoxy block before double-crimping the copper collar. You can submerge the tip in 99% isopropyl alcohol or specialist gel cleanser hundreds of times; the bristle bundle snaps back to a surgical point every time.
An 11 mm liner requires advanced wrist suspension and heavy lacquer tension. For solo technicians and home manicure artists, an 11 mm hair wobbles across the natural lateral nail curve, resulting in thick uneven smiles.
At 7 mm, the filament provides enough reservoir capacity to hold a single drop of gel paint from sinus to sinus, while maintaining the lateral stiffness needed to guide the curve without dragging against the lateral nail fold.
Every brush received from manufacturing is checked by hand under 10x optical magnification at our 130 North Tryon Street workstation. We pull the filament bundle with dry silicone tweezers to ensure zero stray or loose hairs.
Our practitioner has worked in professional salon environments since 2022. Brushes that show even a single flared fiber or a loose cap friction fit are rejected immediately before shipping.
Care & Cleaning Protocol for 7 mm Micro-Liner
Synthetic filaments last over two years when cleaned with proper solvent discipline. Never use pure acetone for daily storage rinses.
Excess Gel Wiping on Lint-Free Spunlace
Immediately after painting, draw the brush flat between a folded lint-free wipe soaked in 70% or 99% isopropyl alcohol. Do not twist or grind the tip.
Deep Clear Gel Conditioning
If color pigment remains near the ferrule, submerge the tip in a droplet of clear base coat or top coat. Work the gel through the hairs, then wipe dry on a pad to carry pigment away.
Reshaping & Cap Installation
Form the hairs into a needle tip using clean gloved fingertips. Slide the ventilated metal cap straight over the ferrule without catching stray side bristles.
No. A 7 mm liner is an art instrument with a 0.45 mm root bundle. Using it to coat full nail surfaces will introduce micro-streaks and destroy your leveling speed.
For applying base coats and sculpting builder gels across the apex, choose our #6 Flat Oval Gel Sculpting Brush ($14 USD). It has the bristle volume and curved edge required for full plate coverage.
