Product name: 10m mapping string preinked Overview Preinked mapping string for precise eyebrow and cosmetic mapping. Each thin cotton thread is precoated with cosmetic grade bamboo charcoal pigment to deliver clear, consistent lines for design and planning. Available in black ink and white ink. Key benefits Ready to use: preinked thread removes the need for separate ink application and speeds up the mapping process. Consistent, crisp lines: even ink coverage along the 10 m length helps produce smooth, accurate guidelines. Thin and durable: cotton thread is thin for fine control yet strong enough for repeated tension during mapping. Easy to clean marks: mapping lines remove with a cotton pad or alcohol pad if needed. Compatible with mapping tools: performs well freehand or when used with rulers, calipers, or other mapping aids.
