Surgical Skin Markers (5 Pack, each pen is 5" long with cap on). The best way to keep your perfectly drawn custom eyebrows in place while you work! These skin markers are fine tipped with long-lasting, anti-fungal gentian violet ink for the safest and most durable permanent cosmetic procedure. Blueprint your design by adding purple dots to the outside edge of your pre-drawn eyebrow design. Allow to dry for 3 minutes before beginning work for the longest lasting results. Removes best with a 5 minute soak of RecoverAll or BlockAid anesthetic.
