The price is for a set of two knobs. This a striking piece of art for your favorite guitar and sure to turn heads. These are all solid copper statement pieces that are 1 1/8" at the base and stand 3/4" high. they fit a 6 mm knurled split potentiometer shaft. If you have a smooth shaft that requires a set screw these will not work. These are the push on style. Please read the description carefully. I will only refund if they are defective and require a 15% return fee for all other returns. I hand make these knobs here in the USA to perfection as ordered. Please check my feedback and buy with confidence. These are large statement pieces
