Two narrow (skinny) knobs for use with potentiometer, encoder, etc. There are two versions of each knob, with and without an indicator mark.
These are good for when controls are very close together and larger knobs would make things too tight, or when a more subtle knob is desired.
Can use a paint pen or nail polish to color the indicator if you'd like it to stand out a bit.
These fit the potentiometer knobs from Adafruit.
