Courreges American Earrings Purchased over 20 years ago at Courreges in a Kintetsu department store in Osaka. I wore them immediately after purchase, but they have been stored in an accessory case ever since. I wiped them with something like a wet wipe with only water before and after wearing them, but I haven't done any special maintenance. I don't think there are any major flaws, but please understand that they are items that have aged and been stored for a long time. There are no boxes or other accessories.
