This is a long-sleeved cotton rib knit innerwear from Uniqlo. Made of 100% cotton, it was very useful. It seems that the long-sleeved version of this product has been discontinued this season, so it's no longer available. I hope to be able to deliver it to someone who needs it. This item was worn by a child, so there are small stains and signs of wear. Please check the photos. The name was written on the tag, so half of the tag has been cut off as shown in the photo. Please purchase only if you understand that this is a used item. We will also post pictures of any stains, so returns and complaints will not be accepted. Thank you for your understanding. Thank you.
