These are not the cheesy magnets you would pick up from the planetarium/science store 10 or 20 years ago. These are high strength magnets that allow you to do amazing things around the house and office.

Do note that because of thinness of these magnets compared to their magnetic strength, you may crack/break them if using a tool (like pliers)to pry them off a surface they are stuck to.

Geeky fun.

I bought these to glue to other items to make frig magnets. They were perfect. I did have one break right out of the box because I lost my grip on it trying to pry it off the stack. It snapped back and cracked in half. To have this type of thinner magnet I am willing to be careful.

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.
