Cone magnets
Cone shaped magnets have a small and a large side. You can read all about magnetism, strength etc. on each product card below. The cone shaped magnets fit many purposes. Use them on magnetic boards with the smaller side on the board for an easier grip on the strong magnets. Place them in a cone shaped hole to make a non-magnetic item magnetic. Or how about making a knife magnet by placing the larger side on the fridge and hanging the knife on the smaller side. There are many options.
