★Please read to the end★ This is a Galaxy Ring Sizing kit, purchased at Yodobashi in December 2025. Used for only one day. ★Please read carefully★ If you are a highly sensitive person who cannot tolerate wrinkles caused by folding for shipping, please refrain from purchasing. I have had a very unpleasant experience in the past with someone making unreasonable complaints despite my following Mercari's official packaging guidelines. Thank you for your understanding. ① I will not accept price negotiations or offers. ② In line with SDGs initiatives, I do not use excessive packaging. ③ I cannot provide the same level of service as official online stores. The following are the basic rules of Mercari, but I will state them for your information. ・All items are shipped via Mercari's shipping service, so I am not responsible for accidents due to shipping issues such as bag damage. Please contact the Mercari office directly if there are any problems. ・Instant purchase is OK, so comments like "I want to buy" or "Is this still available?" are unnecessary. Therefore, even if you leave a comment, I will prioritize those who apply to purchase according to the rules. ・I generally do not create dedicated pages. I also do not reserve items. (I will create combined & dedicated pages for multiple purchases) Please note that by purchasing, you are deemed to have agreed to all of the above.
