Blopens are the ultimate airbrush fun for kids. Blow into the pens from the top, and the color comes out at the bottom. With the four included stencils, small and large artworks can be created quickly. The blow pens impress with their vibrant colors and easy application. The high-quality plastic prevents diffusion. Suitable for children aged 4 and up. Accidental inhalation of the paint is impossible due to a safety membrane. Tip: Unused paint can be reactivated with water and vinegar.
