Our Henna Tottoo set is made from natural ingredients with multiple certificates, no PPD, safe to use. For safety reasons we recommend a short allergy test before use as with all cosmetic products. Apply the henna tattoo evenly on the skin, after drying (about 40 minutes) tear off the stencil and rinse with water. Do not scrub vigorously after the tattoo is coloured. The durability of each tattoo colour is different, brown is about 5 days, black lasts 3 to 4 days. Please do not apply the henna tattoo to clothing, it cannot be washed off. After soaking and rubbing in hot water the colour will fade faster. Pregnant women and people with sensitive skin should not use Temporary Tattoo. Our Temporary Tattoo set includes 2 black and 2 brown tattoos, best gifts for kids and adults, perfect for party, music festival, carnival, Halloween, Christmas and other celebrations.
