Vintage Art Deco Hair Comb. Faux tortoise shell celluloid. 6 。Unique vintage hair comb or clip designed to hold hair in a ponytail or updo. Banana clips are typically elongated and curved, designed to hold hair in a vertical line, creating a \"cascading ponytail effect\" or securing an updo. This clip has a curved, elongated shape with teeth-like structures on the inner curve, consistent with this function. Made with a celluloid faux tortoise shell, material and features decorative rhinestones on one side. It opens to allow hair to be placed inside, then close to secure it, similar to how banana clips or fish-shaped hair clips operate.
