I bought these for Valentine's day one or two years ago. These are lightweight easily bends. You have to be careful not to stretch them out of place. If you look at the picture carefully, you will see that the "knot" in the middle of the heart isn't really a knot, but part of the earring that fits into your ear. Stretch it too far and it won't fit through the little hole, that has no clasp to hold it in place. The material hasn't tarnished yet, but I don't wear them much, as I want to preserve them for as long as I can.
