This unit is perfect cannot express how much this is just what we needed. My wife likes to by these cups of cupcake and cookie decorations and they get forgotten or lost in the cabinet this allows us to keep track and organize the decorations easier and the magnets are very strong no problem sticking to side of my fridge. Most definitely recommend and I myself am getting another because I need more jars just a note depending on side of decoration the one plastic cup kinda equals one bottle.
