This 14/20 yellow gold-filled box chain ear thread features a center U-bar, making it incredibly comfortable while worn. Ear chains are a versatile, fashion-forward option for customers. Use the open ring to attach drops, dangles or other findings or design to complete the earring. Customers simply insert the post to lead the first half of the chain through the ear until it's centered. Gold-filled ear chains deliver karat gold at a more affordable cost than solid gold, allowing you to design with the touch of precious metal customers look for and to offer your designs at a price customers appreciate.
