※ This listing is for dice knobs, not a guitar. The first 1-4 images are for monitoring purposes. There are two knobs, one with the number 4 and one with the number 3. The size of the dice is approximately 15mm in both length 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 stringed instrument before purchasing. There are some imperfections in the black paint on the numbers, and as these are handmade, there may be slight misalignments of the holes, scratches, and dirt. Please understand this. They cannot be attached to vintage Gretsch guitars. The holes are made for current models. A hex wrench is required.
