These snarky brass F U letter earrings are definitely going to turn heads. Remember, tell your conservative acquaintances that the F is for your Grandpa Fred and the U is for your Grandma Ursula. There the one's with the naughty mind! These earrings are just under 2", but with the earring hook, they hang about 2" ☞All Grey Theory Mill earrings are made with Hypoallergenic, Surgical Grade A, Titanium Earring Wire. Titanium has no traces of nickel and is the premier metal for sensitive ears, which is why this metal is used for surgical instruments. ☞Earrings are NOT waterproof. Please remove earrings before swimming & bathing as water temperature and chlorine could compromise the bond between earring piece and post. ☞Raw brass will naturally patina in color over time. If you prefer a bright gold-brass color you can rub them with a jewelry polishing cloth or brighten with lemon juice. A sample of jewelry polishing cloth is included with all brass earring purchases.
