About this item Pro Brow Mapping Kit: With a maximum length of 19.6 inches and a width of only 1 millimeter, the thinner string means no excess ink interference, only smooth and clean lines, accurately, quickly, and perfectly drawing facial lines, ensuring symmetrical eyebrows and improving efficiency. Controllable water replenishment, easy activation of dry ink: If the ink cartridge is too dry, pull out the silicone cap and use the included dropper to add half a drop of water to the sponge tray (do not add too much) to restore a smooth drawing experience. The operation is simple and the effect is controllable. Elastic drawstring, lightweight, durable, and reusable: Equipped with a high-elastic drawstring, it can be repeatedly stretched and reused to meet multiple eyebrow shaping needs; the lightweight pocket clip design makes it easy to carry and use anytime. Portable chest pocket design, convenient and space-saving: The fixing clip on the back of the product can be securely hung on the chest pocket or trouser pocket of work clothes, achieving a convenient, easily accessible experience, freeing up your hands, and allowing you to use it whenever needed. The mapping string is very easy to clean after use. Simply use a clean cotton pad or alcohol and soap to remove the markings (Note: When stretched to 50 cm, do not continue to pull hard to avoid damaging the automatic retraction device of the eyebrow drawing kit).
