A Spinner Ring is made of super duty rubber and designed to make the process of opening a bottle with a speed opener (Inked Opener or Nubbin) much easier, faster and comfortable. Basically, when the opener is in the back pocket, in your pants or skirt, the ring hole should be sticking out and straight up so that you can easily and without looking slide your index finger into the hole, spin it into position, open the bottle and spin right back into your pocket. The Spinner ring is mounted on the ring hole, thus creating a cushioned band around the metal hole; making it work the way it does, and looks great too! Great for professional bartenders, or the home bar enthusiast. Feel free to call our customer service department at 1-877-465-4255 with any questions you might have. Thank you for your business!
