Silver "Which Way?" Dangle Earrings

Fun, unique earrings! A friend of mine made these and I've been selling them to support our local dog park! She said that these are silver but I don't know the purity of them, I'm assuming they're sterling silver. Cut snd curved from a sheet of silver. They can tarnish so expect to polish them once in a while. Then they really gleam! About 1.25" in length.
