These are some of the smallest magnets I've used for welding, but they work well for holding small parts in place. Sometimes big magnets don't work because they're too big, so it's good to have these little devices. They are just over 2 inches long at their longest end and not very thick. They stick fairly well to a hard welding table and work great with small mild steel parts. These parts are beautifully painted and the overall quality is very good. Each side is a different length, giving you multiple positioning options. I'm happy with it, just wish the magnets were a little stronger.
