Posts and backs are TINY, way smaller than any of my other earrings and awkward to take on and off. However, I decided to keep them anyway but when I took off the 14k PAPER tag from one of the backs, my pulling off the tiny paper tag caused one side of the curly parts of the back to uncurl so is no longer usable. Really shoddy design. I guess they wanted to say "14k" but wanted to spend as little $$ as possible.
