Blopens are the ultimate airbrush fun for kids. Blow into the pens from the top and the color comes out from the bottom. With the four included stencils, you can quickly create small and large works of art. 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.
