Anyway, I first saw the idea on Mrs. Rojas Teaches' Pinterest page which then took me to her blog. I found out that this "toolbox" is sold at Lowes and is around $17.
Next, I found some labels that I liked, or you can make your own. I have seen some boxes with great color and all fancy; I chose to keep mine fairly simple so that I can use it with changing classroom themes.
Just another fun way to organize your classroom. Could even work well for a home office too!
