Banana clips are a type of ponytail hair clip named for their shape, oblong and curved slightly, like a banana. On one end there is a hinge, the two pieces feature long comblike teeth that come together as you close it with a simple slip hook clasp. These hair clips are traditionally worn vertically on the back of the head, with the hinge down and the clasp at the top. It is common to see it worn high in the back, like a high ponytail, or low at the nape of the neck.
