These are surgical stainless steel stud earrings. Please check the photos for the size (one square is 1cm, dotted lines are 5mm). Accessories listed for 300 yen each, if you purchase 3 or more, will be calculated as 100 yen each plus 300 yen for shipping, etc. (There may be times when I don't have 3 or more items listed, sorry). Example: ● For 3 items 100 yen x 3 + 300 yen = 600 yen ● For 4 items 100 yen x 4 + 300 yen = 700 yen There is a hole on the side of the stone, but it is hidden from view and secured with prongs. Durability is inferior to commercially available products. The stone may be scratched during prong setting, so please refrain from purchasing if you are looking for a perfect item. I made a lot of these as a hobby, so I'm looking for someone to take them off my hands (*´ω`*) This is a hobby of an amateur. I am selling items I can't use as unwanted goods. #earrings
