You get an amazing number of gorgeous butterflies in this bag! Just imagine putting 144 prismatic butterflies on your notebook... it would look like the monarch butterflies when they finally land on their home tree after migrating. That's where you can't really see the tree, but just a bunch of fluttering butterflies shaped like the tree they have completely covered. These great images are taken from photos of real butterflies. As a fun classroom activity, you could have the kids try and identify each different species. Size: bag of 144 mylar stickers, 1-3/4" by 1-1/4"
