Ink Permanent White Brow Mapping String — Pre-inked 2×100 ft Bottles with Built-in Cutter for Precise Microblading Guidelines

Ink Permanent White Brow Mapping String is a pre-inked, ultra-fine eyebrow mapping thread sold as two 100 ft (30 m) rolls in sealed glass bottles, designed to mark crisp, visible guideline lines for microblading and permanent makeup.

Whether you’re a professional PMU artist, a microblading apprentice, or a beauty studio owner, consistent, accurate brow mapping speeds workflow and improves symmetry. Ink Permanent’s white pre-inked string arrives inside elegant glass bottles with a built-in cutter so you can dispense exact lengths without fraying or exposed ink. Each roll contains 100 ft of heavily pigmented, allergen-free ink on an ultra-fine thread that leaves clear markings on skin for multiple passes.

How does this pre-inked string make brow mapping faster?

The pre-inked thread removes the need to repeatedly dip in pigment or draw freehand, cutting mapping time and reducing interruptions. Because the ink is concentrated on an ultra-fine fiber, single pulls create thin, visible guide lines that last through several strokes. The glass bottle storage and built-in cutter let you measure and cut string quickly, keeping your station tidy.

• Two sealed glass bottles keep threads clean and ready.
• Built-in cutter dispenses exact lengths without wasted string.
• Ultra-fine thread produces thin, precise guideline marks.
• Pre-inked design eliminates frequent pigment dipping.

Will the ink show clearly on different skin tones and textures?

Ink Permanent’s white mapping ink is formulated to produce well-seen lines across a range of skin tones and textures without overpowering the canvas. Heavy pigmentation on the thread ensures visibility on both fair and deeper complexions, while the fine line width supports detailed shaping and measurement. Results depend on skin oiliness and preparation, so cleanse and prep skin for best contrast.

• White pigment contrasts with most skin tones for accurate guides.
• Fine line width helps preserve natural-looking brow frameworks.
• Works well on prepared, clean skin for optimal visibility.
• One thread can mark up to 10 lines depending on pressure and skin.

How durable and safe is this mapping string for studio use?

Each roll is soaked in allergen-free ink and sealed in a glass bottle to maintain cleanliness and shelf stability. The string’s heavy pigmentation is engineered to leave multiple clear marks while minimizing residue on tools and work surfaces. As with any tool used on clients, follow standard sanitation protocols and single-use guidelines for best practice.

• Allergen-free ink reduces potential for irritation (follow patch tests).
• Sealed bottle storage keeps thread sanitary between sessions.
• Heavy pigment concentration supports multiple guideline passes.
• Glass bottle with cutter streamlines single-handed dispensing.

How much product do I get and how should I store it?
