This is a BWL Happy Face bracelet. The size is free size, but it's about 20-21cm. I'm selling it because I bought a different bracelet. I used it for about 2 years and wore it almost every day, so there might be some scratches, but I don't mind them myself. However, please check the photos and refrain from purchasing if you are concerned about the scratches. It is an authentic product. Returns are not accepted after purchase. Thank you.
