Before I ordered i went through the all reviews to understand what size I need. I measured mine at home as I needed something that can hold all my hair up. I got an large one. Im satisfied with the size, my hair is medium length but quite thick and with this clip it holds it up. I like it because it doesn’t give me a headache like some other clip do. Some good brands has a metal stuff inside which gives me a headache plus it pulls my hair. Balmain hair clip doesn’t have any metal which makes it light and gentle on my hair. It does look stylish as well. I am thinking to buy one more for myself in different colour. The reason why i put 4 starts- pricing, I think it is too expensive, however if it last for many years it will pay off.
