2-pack Guitar Potentiometer Knobs: Clear Red Dice
This is a set of two clear, round-cornered 19mm red dice knobs drilled to fit 6mm knurled potentiometer shafts. These make a great accent when added to your cigar box guitar, amplifier or other special build. These dice knobs are drilled smooth inside but fit very snugly onto a knurled 6mm shaft, and in our testing they do not slip. You can always add a touch of glue or epoxy if you want to be entirely sure. These are drilled such that the number six side points up.
