I use these magnets to attach small specimens of enamel and metalwork to sheet steel for reference and use in jewelry clasps. They meet all the requirements exactly and I am very happy with the purchase. But a word of caution: the image used on this product is misleading. What I've shown here is exactly what you get: a box of 300 tiny magnets that almost fit in an envelope. The picture shows a much larger block of these magnets. If you really had that many magnets, you would buy 2886 magnets, not 300, and it would cost you closer to $100 than 10. It's fine, but it would be nice to see the real product shown.
