Ink Permanent White Brow Mapping String 100 ft Spool — Pre-Inked, Bamboo Charcoal for Microblading & PMU

Ink Permanent White Brow Mapping String is a pre-inked, mess-free eyebrow threading tool designed to mark precise, visible guide lines for microblading and permanent makeup.

Professionals who shape brows need marking tools that are quick, accurate and tidy. This 100-foot (30 m) spool of white mapping string arrives pre-saturated with pigment and bamboo charcoal, ready to create thin, long-lasting guide lines without reaching for an extra pencil or marker. A built-in cutter and smooth, consistent ink delivery make it practical for busy salons and training sessions.

How does this string speed up the brow mapping process?

Because the string is already infused with pigment, you skip the step of applying ink or drawing bulky pencil lines. One pass can leave several visible strokes depending on pressure, reducing setup time while maintaining crisp guides for shaping or microblading.

• Pre-inked with pigment and bamboo charcoal for immediate use
• Thin, even marks reduce the need for correction
• Built-in cutter lets you measure and trim quickly
• One thread can create multiple lines with a single dip/action

Will the markings stay visible during the procedure?

The formula is designed to produce clear, non-smearing guide lines that hold up through mapping and initial strokes. It’s created to be visible enough for accurate placement while remaining easy to remove after the service if needed.

• Ink formulation minimizes drips and smudges
• Visible on a range of skin tones thanks to concentrated pigment
• Leaves fine, controllable lines suitable for detailed work

Is this suitable for microblading, PMU training, and salon use?

The spool of white mapping string is intended for professionals and trainees who require consistent marking performance during microblading, permanent makeup, or shaping appointments. Its length and durability make it convenient for multiple clients without frequent replacements.

• 100 ft (30 m) spool supports repeated use across appointments
• Durable thread resists fraying for smooth application
• Compact spool with built-in cutter for efficient workflow

How do I use and store the pre-inked string to get best results?

Use the cutter to trim the desired length, stretch the string gently and press it against the skin to transfer a thin guideline. After use, close the spool and store it in a cool, dry place to preserve ink saturation and prevent contamination.

• Measure and cut with the integrated cutter for consistent lengths
• Apply with steady tension for even pigmentation transfer
• Store sealed away from sunlight and moisture to extend life
