While walking through a friend's classroom this week I spotted these little beauties! They are magnetic containers she has stuck to the side of her file cabinets. Genius! She is currently using them to store magnetic letters, but the possibilities are endless. I LOVE finding extra storage in places that don't take up any real space. She said she picked them up at Target in the Back-to-School section and they were designed to be used in student lockers. I suspect they might be hard to find at Target now, but I did a quick Google search for magnetic locker holders and found a variety of similar products to choose from. Time to shop!
