Our eternally popular hoops close with a Y closure mechanism. The post through the ear clicks down into a Y shape. If it gets loose, please squeeze the bottom of the Y. If it’s too tight, simply put your fingernail down into the Y to loosen it up a bit. People who wear our posts tend to wear them all the time. They will get loose simply by repetition of wear. It’s a pretty straightforward process, but please feel free to contact us for an explanation if it is at all confusing.
