Please read the profile for trouble avoidance! Purchase constitutes agreement. Round rings 10 grams 6mm x approximately 146 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 it as a handmade part for accessories, straps, etc.? I am also exhibiting various other items!! If you purchase multiple items, I will also offer a discount. (There are items that can and cannot be combined, so please contact me via message in advance.) I will also be listing items with a mix of different types for trial use in the future. Thank you for your consideration(^^♪
