Please note that I am an amateur and cannot provide a thorough explanation. Please make your purchase based on your own judgment. These are some kind of pearls from when my siblings were in a band. I have no idea what they were used for, so I ask that those who know more about them please take a look. I believe they have been stored for about 20 years, so please refrain from purchasing if you are overly concerned about their condition. Please understand and agree that there will be no claims or returns after purchase. I hope to do business with someone who can make a purchase with peace of mind. I will be deleting this listing after about a year, so I appreciate your interest. (Listed December 2023)
