200PCS 3x1mm Mini Disc Magnet - 3mm x 1mm, Pack of 200 Refrigerator Magnets, Fridge, Office, Whiteboard Magnets for Crafts,Office, Kitchen

These are very tiny but extremely strong.

These are 1 mm thick, and I am using them to hold a pair of pince-nez style reading glasses against my regular glasses. I have used epoxy to glue the magnets to the frame of my glasses and to the lightweight plastic readers, so I can easily attach the readers to adjust my vision for convenient use of the computer. The magnets are quite strong for their size, but remember that they are *very* small. They will not hold a lot, so have realistic expectations for them.

So far so good

My son used these on his Warhammer 40 K models to make the weapons interchangeable. He loved them and it worked well.

Making a doll house with furniture out of cardboard. Holds the cabinets together nicely which was my sole purpose for buying them

They stick to iron and steel and magnets, like a proper magnet should. I am using them to build poseable miniatures.

These came packaged in a convenient plastic storage case. Good for small arts and crafts projects.

I purchased these to use for tracking a motor's RPM using a hall effect sensor (which works well with other magnets). These magnets are too weak to register even when manually held in front of the sensor except when using two magnets together.
