This listing is for clear orange dice knobs, not a guitar. (White dice knobs are not included.) The images are for illustrative purposes. There are two knobs, with the numbers 4 and 3. The dice size is approximately 15mm in both height and width. The set screw hole is in the middle, approximately 7.5mm from the edge. The hole diameter is 6mm, so please check the diameter and length of the knobs on your instrument before purchasing. These are handmade, so please understand that there may be slight variations in hole alignment, scratches, and imperfections. These cannot be attached to vintage Gretsch guitars. The holes are drilled for current models. A hex wrench is required.
