Yes, our temporary tattoos at minink are definitely waterproof. So you can wear them while swimming, going to the sauna or doing sports without any problems.  However, it is important to note that the intensity of your tattoo's color may fade a little faster with frequent swimming. On the other hand, the color of your tattoo can become even more intense when you are in the sauna or sweating. Also make sure that you avoid contact with water immediately after applying the tattoo so as not to impair the development of the color.At minink, we attach great importance to quality, durability and customer satisfaction so that you can enjoy your temporary tattoo for a long time.
