This is a set of 23 long-sleeved T-shirts, with two shirts per pack. Regarding the sizes, as is often the case with children's clothing, the actual size may differ from the size indicated on the label. For example, a size 100 might be larger than a size 110. Therefore, this is a mixed set of sizes 100-120. This would be a great deal for someone with daughters who currently wear sizes 100 and 120. I have visually inspected the items for stains, but there may be some with names written on the inside or with tags cut off. Due to the large number of items, I cannot answer detailed questions about actual measurements. I will not sell items individually. Please understand that these are used items. If you are not accustomed to purchasing used items, please refrain from purchasing. No claims or returns accepted. I think this is a great price! Thank you.
