Clear orange dice knobs. (White dice knob and guitar are not for sale.) The first 1-3 photos are for monitoring purposes. There are two numbers: 4 and 3. The size of the dice is approximately 15mm vertically and horizontally, and the side hole for the set screw is in the middle, about 7.5mm. The diameter of the hole is 6mm, so please check the diameter and length of the knobs on your stringed instrument before purchasing. These are handmade, so there may be some misalignment of the holes, scratches, and dirt, so please understand. They cannot be attached to vintage Gretsch guitars. The holes are made for current models. A hex wrench is required.
