When it comes to leaving sticky notes behind for someone else to read, most of us would be happy enough with a regular yellow colored square. After all, that is what the majority of the older office folk grew up with, but this does not mean that there are no ways to bust out some creativity, right? How about bringing some much needed cheer to a somber office setting with the $7.99 Rainbow Sticky Notes? These will provide the touch of happiness required to brighten up any day, where you can make use of an entire spectrum of colors. Each purchase comes with 100 sheets of rainbow shaped self-adhesive memo notes and a cardboard easel back.
