I bought these for sharing files, but I have a lot, so I'm selling some. 20 silver pieces. Simple packaging, just putting them in a bag without wrapping them in bubble wrap. 50 pieces for 559 yen, shipping via regular mail is also available. Please contact me via comments. ■These are made overseas, so the quality is not like that of Japanese products. Since they are unopened, I have not inspected them, so please purchase with your understanding. If you are looking for a perfect product, please refrain from purchasing. ■Shipping will not have insurance, so I cannot provide compensation for any accidents. I cannot accommodate urgent shipping or date/time指定. I will ship within 2 days in principle. I cannot respond to comments requesting these services.
