Please read the profile for avoiding any trouble! By purchasing, you agree to the terms. Round rings 10 grams 9mm x approximately 33 pieces I don't know the details of the material, etc. Please refrain from purchasing if you are nervous or seeking perfection, as this item has been stored for a long time. How about using them as handmade parts for accessories, straps, etc.? I'm also selling various other items!! We will offer a discount if you purchase multiple items. (Please contact us via message in advance, as some items can be combined and some cannot.) I plan to sell mixed sets of various types in small quantities for trial purposes in the future. Thank you for your consideration. (^^♪
