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 worn, but it has never been worn. I bought it, washed it, and then washed it again at the end of summer, and then washed it again at the beginning of summer, repeating this process for several years. It has been hanging on a hanger, so there are creases on the collar, and it is slightly white. See photo 6. The collar is not stained with sebum from wearing it, so I haven't washed it specifically. It is air-dried indoors. It is stored in photo 7. You can purchase it immediately without any comments, such as "Is it available for purchase?" within 24 hours. It will be shipped via anonymous Nekopos. I will not respond to price negotiations. If you wish to purchase multiple items, please comment with A and B instead of requesting a combined purchase. I will accommodate your request. I will discount 200 yen for two items, 400 yen for three items, and so on. It is acceptable if the weight is under 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 first will be given priority. I will ship the item using materials I have at home, ensuring that the product is not wet or damaged. Please refrain from asking questions if you are not intending to purchase the item, or if the questions are unrelated to the purchase, or if you are asking about items that are not listed, or if you are asking "I am considering purchasing, but how much can you lower the price?" Sometimes, the photos and descriptions may differ. It was a mistake, and there was no intention to deceive. If you feel uneasy about the product description, or if you have any complaints, or if you are the type of person who intends to leave a negative review, or if you are unable to properly evaluate the receipt, please refrain from purchasing. Also, please refrain from purchasing if you are particular about the packaging or the way I handle the transaction. You are welcome to cancel the transaction during the transaction, but please do so before shipping. Cancellation 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, or to ask about things that are not written, or to ask questions to get a discount, or to get attention. Please conduct transactions without causing any inconvenience.
