Authentic goro's Large Feather with Metal Brand: goro's Product Name: Large Feather with Metal Material: Silver, 18k Size: Approximately 6.8 x 1.5cm Please note that there may be slight variations due to amateur measurements. Condition: It has been worn, so it has sulfurized, but I polished it slightly when listing it so as not to ruin the atmosphere. I will send it as is, so please check the photos. Accessories: Item only Weight: Approximately 10g Purchase Location: Purchased by myself at a certain consignment store I purchased and wore it around 2010 at a certain consignment store in Harajuku. It was easier to buy back then, and I enjoyed collecting them. The hole is the current type, so it can accommodate fine, thin, thick, and thick chain. I am thinking of organizing my collection, so I will sell it at a relatively low price. I have worn it with care, so I would like to pass it on to someone who needs it at a price I can agree with. However, as you know, goro's is subject to various opinions and differences based on store standards, so it is not necessarily not authentic just because an appraisal is not given. If you have any concerns, please refrain from purchasing to avoid any trouble and purchase from goro's or a store you trust. *Please understand that there may be some color differences from the actual product due to the lighting conditions during photography. *Regarding Authentication I basically only sell items that I have purchased from a source I trust, as stated above. I believe that the issue is with the standards, so I will not respond to authentication requests because it would be troublesome to have a transaction fail for that reason. Please consider purchasing based on your own judgment. Thank you for your understanding. Please read the profile before purchasing or commenting. Thank you.
