These are earring parts. I used to use them sometimes when making items for giveaway promotions, etc. They might also be good for bazaars. I'm not using them for crafting anymore, so if anyone is looking for them, here they are. There are 90 pieces. They are not pairs, so if you consider them as pairs, you'll have 45 sets. Some discoloration can be seen depending on the angle. It's not a noticeable discoloration like gold, but those who are concerned or plan to sell them in a shop might not find them suitable. They will be shipped by standard mail. Please note that these are items stored at home, so we appreciate your understanding before purchasing.
