NOTE: please note i do NOT play grade only VISUAL grade i also DO NOT clean any vinyl, i also recommend for the buyer to have a cleaning machine when buying old vinyl, sometimes a LP will look NM but when played it can have some crackle/noise this is because the LP is 50-60 years old and most likely needs a professional clean once clean the LP should play NM.
I am a very strict grader and i highlight any visual marking i see to LP.
