I bought these to attach to my handmade Christmas decorations so they will stick to metal surfaces. I glued the magnets to the back of the jewelry using E6000 glue. I found the magnets were dirty when I took them out of the box so I wiped them down with a cloth before using them on my project. I measured the magnet and they are 1 inch in diameter and the thickness of two nickel coins stacked. I originally thought they were thinner based on a question I posted here on Revain. However, they still fit my craft project.
