Henna: Simply Red Temporary Tattoo These paisley henna print temporary tattoos have a classic, understated feel. They make the traditional dying of the skin involved in henna tattooing simpler and safer. The semi-permanent staining of henna is gone and the wait time is seconds instead of hours. It takes 30 seconds and just a little water to apply the tattoos. The bold lines and designs of classic henna are still here, too. The round designs work well on backs and shoulders. The leafy armbands might be the accent you're looking for on an ankle or wrist. The design and placement of your temporary tattoos is up to you and your imagination.
