This is a purple DRT Varial knob. Everything in the photos is included. I purchased this used previously, but I have never used it myself. I decided to sell it because I recently bought a different knob. Also, a T30 tool is likely needed when dyeing the knob cap. Please note that we cannot offer a discount on this product.
