Product details Madewell: In partnership with our friends at To The Market, this superspecial jewelry collection was handmade by Kenyan artisans using old-school techniques and upcycled raw brass (see: old padlocks and water taps sourced from scrap yards). In our hoop dreams: these bold statement earrings crafted from linked circles. 30 mm. Brass. Due to the nature of the material, raw brass will tarnish, so keep away from water and wipe clean with a jewelry polishing cloth.
