Please refrain from asking questions if you have never worn Adidas men's clothing or are unfamiliar with Adidas men's sizing. The collar is a bit worn, but I have never worn it. I purchased it, washed it, washed it at the end of summer, washed it again at the beginning of summer, and have repeated this process for several years. It has been hanging on a hanger, so there are creases in the collar, and it's slightly white. See photo 5. The collar is not stained with sebum, so I haven't washed it specifically. The lower left back, and the center right area are slightly white. See photo 6. It is air-dried indoors. It is stored in photo 8. You can purchase it immediately without any comments, such as "Is it available for purchase?" 24 hours a day. It will be shipped via anonymous Nekopos. I will not respond to price negotiations. For multiple purchases, instead of requesting a combined purchase, please comment with "A and B" if you want to purchase multiple items, and I will accommodate. I will discount 200 yen for two items, 400 yen for three items, and so on. It's okay if the weight is up to 1 kg and fits in an A4 envelope. To avoid trouble, I do not offer reservations, holds, delayed payments after purchase, or specified shipping dates. In any case, the person who purchases the item will be given priority. I will use items I have at home to package the item so that it doesn't get wet or damaged during shipping. Please refrain from questions that are not intended to purchase, such as "I'll consider it," questions unrelated to the purchase, questions about items not listed, and comments like "I'm considering purchasing, but how much can you lower the price?" Sometimes, the photos and descriptions may differ. It was just a mistake, and there was no intention to deceive. If you feel uneasy about the product description, or if you have any dislikes, or if you are the type of person who intends to harass, leave a bad review, or cannot properly provide a receipt evaluation, please refrain from purchasing. Also, please refrain from purchasing if you are particular about the packaging or the way I handle things. You are welcome to cancel the transaction during the transaction, but please do so before shipping. Canceling after shipping will cost the buyer both time and money. I am trying to provide a detailed product description so that there are no questions. Please refrain from asking questions to confirm what is already written, asking questions to find out what is not written, or asking questions to get a discount or to get attention. Please conduct transactions without causing any inconvenience.
