The Fridge Pen

I recently discovered that four quarter-inch (1/4") neodymium disc magnets (“rare earth” magnets) will not only fit nicely inside the body of a Bic pen, but they are strong enough to hold both the pen and a shopping list to my refrigerator:

Perfect! The list and the pen will always be right where I want them. And I can just use scrap paper for lists instead of buying ridiculous magnetic notepads. I had disc magnets on hand, but I bet a cylinder magnet would be a great choice as well. You might have to trim a bit off the ink sleeve to make room for the magnet in the barrel (hasn’t leaked on me yet, even when you trim down to where there’s still ink).
