Applications:

These tiny magnets come in a unique and practical size—small, affordable, and easy to stock up on. Despite their size, they’re remarkably strong, making them perfect for hanging photos or lightweight materials on metal surfaces. Just one or two can securely hold a picture in place while staying almost invisible.

They also demonstrate fascinating behavior when used near larger magnets, making them fun for experiments and creative projects.

In tests on flat steel surfaces, a single magnet held over 7 ounces, more than 2,000 times its weight. Truly impressive performance for such a small piece!
