Sometimes you need to sneak up on someone and drop a sticky on them without being seen. Just like a ninja, except without that whole killing the other guy part (I know, I know, words are man’s deadliest weapon). Well stealth up your notes with Ninja Sticky Notes, which are just like Post-Its except black and shaped like ninja and ninja stuff. Each pack comes with 3 different throwing stars and one ninja (six sheets of each). You might be asking how you are expected to write on a black paper- you’ll figure it out, you’re a ninja after all (or you could just use a silver sharpie or crayon).
