This clever collectible activity allows you to make your very own light up liquid glitter pen! The floating "Pen Pal" character, Frankie Fangs the surfer shark, gives each pen personality. Add in the glitter, plastic beads, printed plastic shape and mineral oil and screw the pen shut. Watch Frankie swim up the pen as the other elements cascade to the bottom. Pen lights up when you press to write! You will want to collect all 4 styles!
