This is a set of approximately 1000 flat, can-less, 8mm stud earrings and approximately 1000 earring backs. You can choose one type of earring back from two options: butterfly backs or bell backs. Flower-shaped resin backs are currently out of stock. Please be aware of this. Please comment with your preferred type of earring back, either before or after purchase. The quantity is managed by weight, so the number of pieces is approximate. Also, the number of earring studs and backs may not be exactly the same. Please understand that there may be some variation in the number of pieces. The earring stud size is approximately 8mm, but there may be some error in the actual size due to amateur measurement. Please check the 4th photo for the size of the parts. The color of the earring studs and backs is gold, but please note that the shades may not be exactly the same. They will be sent in simple packaging via Yu-Packet Post Mini. These are imported products from overseas. Although they are unused, the "product condition" is set to "like new" due to the imported nature of the items. There may be peeling, scratches, chips, dents, and size variations. Also, other parts may be mixed in during the manufacturing process. Please understand this beforehand. Can-less flat stud earrings, earring backs, set, gold, 8mm, choice of backs
