ILLUSTRATED FITTED TO A TYPICAL CHIN REST. CHIN REST NOT INCLUDED
Grade 8+
Uncomfortable.
Pros: That they were separate
Cons: The lower end was too chunky and not smooth, so they were too uncomfortable against my collarbone. This may not be a problem for someone who places their chin rest centrally above the button. I was mistrustful of the long term strength of the plastic feet.
