It's a solid machined aluminum knob, with knurling on the sides for grippyness, and a shiny anodized coating. It looks like the type of knob you'd find in a suped-up recording studio. There's a black triangle on the finish so you can know where you are and figure out where you're going. Adafruit have these in a few different color

**This knob has a set screw that uses a 2mm hex wrench (not included) which means it can be used with *any* 6mm shaft rotary encoder or potentiometer: T18, round, D-shaft!** Simply loosen the set screw, press onto the shaft, and tighten the set screw so it no longer rotates.
