Lightweight but heavy in style and quality!
Color: Black+White
Bracelet fits well on wrist, not too heavy at all pretty light, easy to put on and quite stylish! It’s shiny and has great quality for being so lightweight. Wore it for awhile and it’s both comfortable and dressy! Simple jewelry but its use of cool shapes makes it seem quite expensive!
