Magnet only attracts pivots so I assume they are copper as advertised. But they're varnished or something, I really had to pry each one up with a small screwdriver to open them first. After that, they're really hard to open with your fingers, as there's very little mechanical advantage due to the tiny area your finger can press on from above, and the hinge and spring feel very stiff and grainy. Vinyl boots are slippery on the inside, which adds to the fun. Bad design, bad execution, avoid.
