I started doing this when I got my first locker in 6th grade. I would buy my favorite kind of almost anywhere jar for my locker. It keeps it smelling fresh and clean. It can stick onto your locker in 2 ways, suction cup or magnet. The magnet works best, but the suction cup is fine as well. My little 7th grade cousin is glad she came to Yankee candle with me. She got vanilla cupcake and said everyone was coming to sniff it. It is definitely one of my greatest and smartest ideas.
