The “O-NUT” cylindrical earring back is an innovative jewelry accessory for stud earrings that puts a new spin on traditional ways of holding earrings securely in place. When used correctly, its design makes it safer to use, since it is less likely to slip off. Unlike other earring backs, this system uses pressure, so it cannot gradually loosen with wear or slide off if the earring is pulled. Additionally, the product’s tubular shape makes it easier to handle and to clean inside and out. Its simple and minimalistic design is different from the traditional and rococo earring nuts. While this small accessory is often overlooked, “O-NUT” offers a solution that is both functional and aesthetically pleasing.
Designed and handmade by Tissa Berwanger. O-NUT´s first prototype was in 2007. O-NUT is easy to manufacture industrially in gold, silver or even steel, it is comfortable to wear and to store.
