Discover creative fun with the Dinosaur Blow Pens! Decorate the T-rex, Stegosaurus, and Triceratops with the 4 included blow markers in turquoise, yellow, orange, and purple. Use the pens as regular markers or place them in the holder to create a beautiful airbrush effect – the choice is yours! Wash the dinosaurs with water and the sponge so you can reuse them next time.
