This is a brass bangle from the jewelry brand "nibi." I used it as a men's accessory, but I think the brand is more popular with women. It's a unisex brand. Brass is rare now as they mainly sell silver. There are some areas with a slight blue tarnish, but this is characteristic of brass. It can be cleaned up with maintenance. - Material: Metal - Design: Embossed - Shape: Open bangle - Color: Bronze - Size: Free size
