The look awesome
I use paint I mix from pigment I get on Culture Hustle USA and then sprinkle these on the pictures to make them really, REALY bright under a uv light. Very fun.
Our family has been a big fan of Glo Pals for a few years and were excited to see that our local science shop was carrying them. They make bath time so much fun!
Absolutely lovely little pin! Iguanodons are my favorite dinosaur so it's nice to find something that I can rep my love for them with!
