Small, powerful, unlimited applications, Caution, very brittle and definitely not a toy

Ordered, 1.5 working days later "glued" the envelope on the inside of the letterbox flap. Literally.
I am surprised so seriously that the Post has no problems with the delivery of such a strong magnet.

Very practical things.
Can you without problems etc. also a multi-folded flyers with the Magnetpinwand or the refrigerator door, the fuse box with "Staple" when you stack a plurality of magnets, even a small block.
If you think about something, come to mind countless other applications. Attached did, as just one example, on my flashlight (only) 3 This mini magnets, now I can fix on any magnetic surface. The creativity are there no limits.

However, some caution is required; the material of the magnet is very brittle and breaks / shatters easily. This can happen even if you approach two individual magnets on the table and then "crashing". Therefore, definitely not a toy for small children, even if it's fun.
