These are the magnets
I have been using (I need to buy more).
I love having a steel bus. I also like having a steel medicine cabinet.
I have glued a magnet to the lids or backs of medicine bottles or used clear packing tape to tape a magnet to the back of a bottle. Almost everything in my medicine cabinet is stuck to the metal in it. I even have a magnet taped to the inside of the boxes of bandaids and cold medicines. This way I don't have to worry about things falling out of the medicine cabinet when I open it. Everything stays in it's place. Plus I can stick things above short things and still remove the bottom thing. Even my toothbrush is stuck to the door of the medicine cabinet (in 1/2 of a plastic toothbrush holder with a tiny drain hole drilled into the bottom, just like the one that holds my razor handle). Binder Clips (also very handy) that I buy at Sam's Club (because I go thru them so much) are clipped to tubes of medicine and stuck to the steel door. The black stripes - Gorilla Tape - on the door shows me where the edges of the cabinet is and where the shelves are so I can position the stuff stuck to the door. The door of the medicine cabinet is held closed with magnets.
Love them magnets
