I don't remember how many years ago it was, but I've kept this item stored away without ever wearing it after purchasing it. I'm selling it because I don't plan to wear it in the future. This is a set of two items. ・UNIQLO UV Cut Stretch Broad Shirt (Three-Quarter Sleeves) White, Size S ・TOPVALU Regular Silhouette Shape Retention Shirt (Short Sleeves) 7R Both items are new and unused, but they are considered pre-owned as I have opened the bags for the listing. I didn't see any yellowing when I unfolded them, but I haven't thoroughly checked the inside, so please be aware of that. Although they are unused, there may be some wrinkles from storage. Please refrain from purchasing if you are sensitive to this. If you understand the above, you can purchase immediately. Please feel free to comment if you have any other questions. Thank you.
