Cool looks for cool appearances. Kids love to paint themselves and they love cool looks. To ensure everything is carefree and safe, there are special pens: With the four KREUL Tattoo Pens, painting on the skin becomes a colorful fun. The artworks last a few days depending on skin type and are a real eye-catcher at children's birthday parties, family celebrations, during carnival and Mardi Gras, in summer at the beach, and when princesses and pirates want to dress up. The pens contain water-based cosmetic ink that is dermatologically tested. They are free from parabens, vegan, and easy to use: The flexible brush tip can be easily applied directly to the grease-free skin or shaped with the appropriate tattoo stencils. The KREUL Tattoo Pens are not waterproof. They are perfect for children because the ink can be washed off the skin with water and is removable from most fabrics at 30 °C. We recommend applying tattoos only in areas where sweating or contact with water is minimal. So, better on the upper arm rather than on the wrist.
