Nostril screws are an alternative to nose bones, nostril rings, and nostril hoops. Most are held in your nostril piercing by a small loop which sits inside your piercing. Some are unbent so they can be custom fit for you. Fans of nostril screws like the feeling of extra security the inner loop provides. Like nose bones, nostril screws are small and typically are fairly discreet. Nostril screws are a beautiful way to show just a touch of color or the glitter of a gem in your nostril piercing. Nostril screws are available in stainless steel, titanium, acrylic, glass, or 14k gold.
