Please read the profile to avoid any trouble! By purchasing, you agree to the terms. Round rings 10 grams 12mm x approximately 50 pieces I don't know the details of the material, etc. Please refrain from purchasing if you are nervous or seeking perfection, as this is a long-term storage item. How about using them as handmade parts for accessories, straps, etc.? I'm also selling various other items!! If you purchase multiple items, I will offer a discount. (Some items can be combined and some cannot, so please contact me via message beforehand.) I will also be listing mixed sets of various types in small quantities for trial purposes in the future. Thank you for your consideration. 😊
