Inkbox Freehand Ink comes in an ergonomically-shaped bottle with a stainless steel tip. Turning your art into ink, it’s the ultimate vessel for creativity. Simply draw your masterpiece on your skin, let it sit for 1 hour, and then wash off. Your tattoo will appear light at first, but it develops and darkens over 24-36 hours. The result is the look of a real tattoo for 1-2 weeks.
