It's light and easy to put on, making it very convenient. But when you wear it, it becomes modern and very stylish and wonderful. I don't know what the material is. I've used it quite a bit. It has a certain amount of wear and tear, but it's on the neck strap, so it's not visible at all. The length from bottom to top is 40cm, which means it's 80cm in total. It's a designer item and was quite expensive. But I've used it quite a bit, so I'm selling it at a low price. It can still be used, still.
