The nut in a nut, the famous turner's puzzle. Made from a solid hexagon stock. The external nut is 1-1/4", or 31mm. The internal nut is about 3/4" with 1/2"-13 threads. The internal nut rotates freely, but can't go out. You can customize the item with adding your own text. Your text can be engraved on one side, or on both sides of the external nut - see photos and video on YouTube. Engraving your custom text would cost extra 50 cent per symbol to the base item price. You're paying for the real symbols - letters, numbers, but not for the space intervals. The maximal number of characters that can be put on one side is 30 (including space intervals) - see pictures attached. The item is being sold with a piece of high quality stainless steel chain.
