This cute vampire bat is all smiles and rainbows... He swears! Comes in a large range of sizes so you can buy them individually or take advantage of the Bat Pack (same size) Bat Pack (assorted) or Colony assortment to build a flock that's perfect for you.

It’s really easy to apply, just peel and stick to your window. It even comes off without residue because it is a static cling so you can try it in different places to figure out what window gives you the most rainbowy goodness without worrying about damage to rented spaces.
