I bought these to hold an aluminum gas door closed on my truck after the original spring broke. They show a picture of the magnets holding together through a penny so I figured I'd give them a try after using hook and loop first and having it fail due to exposure to the elements. I got the tiny 1/4 inch ones and used epoxy to clue them on the door. They worked so perfectly and I found so many other uses for them I actually ordered two different sizes to add to my collection. They are so strong that even the tiniest ones will hold through multiple sheets of paper on your fridge, I've glued them to bottle openers and also to my BBQ tools to stick right on the side of my grille. I love these things and can't believe I never discovered them before.

Here's what you do: get 30 plastic push-pins like folks use on cork-boards.

Light a candle, and hold the tip of a pin over the flame for 5 seconds (be careful, etc.), then pull the heated metal pin out of the plastic with pliers. With a few strokes across a file, make sure the bottom of the plastic (where the pin used to be) is flat.

Lay out your 30 magnets, keeping a generous distance between them as they will "jump" at each other and mess up your work. Mix up some 5-minute epoxy and put a very small amount on the plastic, then squish it down onto a magnet. Repeat until you have an armada of thumbtack magnets.

Once the glue is set, carefully carry the magnets to your fridge and try them out. The magnets really like to be in a stack with one another, and may destroy the plastic you've just glued on if several are loose together. This won't be an issue once they are stuck to your fridge door.

These magnets are exactly the right size for this application, and the thumbtack handle makes them very easy to place and remove.

We were constantly having problems keeping all the coupons, invitations, photos, and school projects on the fridge with the cutesy, funny or freebie magnets in our arsenal. We got these to make things stay put.

And they do. These magnets are small, but they are very, very strong. Only trouble is trying to get one separated from the rest! Now all of our refrigerator art is securely fastened to the door.
