You get 8 (Eight) 3D printed fender style knobs in chalk blue color PETG food grade plastic.  I designed these in Fusion 360 and printed on a Prusa MK4 which means you won't find these knobs from any other seller.  

You can paint the indicator line with an enamel or acrylic paint.  These knobs are super nice and higher quality than what came on my Fender Rumble 200.  They fit nice and snug and could be used on a variety of amps with D style potentiameter pots.
