These appear to be very strong magnets. I use them to keep my place in my knitting pattern and they work very well to hold down the pattern and to keep my place.

Bought these to put on a standalone cabinet/pantry. The single magnet that came with it was not sufficient to hold the metal doors closed. These came with peel off stickers, so I was able to attach them to the doors in a few spots. They hold tight with a strong bond.

Magnet Strength - 5 stars - Very strong magnets Magnet Durability - 2 stars - Extremely fragile. One broke easily. Use caution.

Product was of quality and strength to provide necessary effects of closure.

These are really cool and my munchkin loves them, but they're very fragile and 2/5 were broken in the box
