these have so many different uses. i use them for many things like to adjust battery size for my flashlights, easy attachments of some things to peg board, etc
13mm is approximately a half-inch. So 3mm is less than 1/8 inch. Very small & thin wafer. You can salvage magnets this size from old earbuds.
There are other sizes with some larger magnets available from another Hong Kong website:
Also search on eBay for Neodymium, or NdFeB Rare Earth.
Caution: The larger magnets will attract each other with great speed and force, possibly resulting in pinched fingers or broken magnets. (These magnets are brittle, so the thinner the magnet, the more likely it may break. For 10mm or larger, get at least 5mm or thicker.) I have ordered from DX.com site and have been happy--Free ship; but be prepared to wait a couple of weeks or more for arrival of your order since it arrives from Asia. --RRR
