Thank you for reading my listing Description! Item specs as below Measurement: 18mm x 15mm Material: Brass, Gold Filled Quantity: 1 Piece Lead & Nickel Free Please avoid chemical solutions, perfumes, excessive sweat, ocean water & swimming water. Salt water & chlorine can damage your jewelry. Chlorine can damage & discolor metals that are alloyed with the gold & can slowly erode the finish & polish of gemstones.Also, lotions & sprays create a film on the jewelry, making it dull & dingy. To keep any tarnish or wear from setting in, take a soft, damp cleaning cloth & gently wipe off the surfaces of the jewelry, being sure to get in all the nooks & crannies. Keep jewelry dry. Moisture is the main factor that speeds up the tarnishing process. Store different types of jewelry separately. We recommend using a Ziploc or sandwich bag with the air squeezed out to prevent oxidization.
