The weight is average, and it seems durable. The second photo is a wearing example. As the photo shows, it's a necklace that's not too long, so it would be better suited for tops with an open neckline, like half-zip shirts or shirts, rather than pullovers or turtlenecks. It's the type that you put on from the front, so it's easy to put on even when you're in a hurry, which is also appealing. The heart is cute!!
