This is a set of 5 long-sleeved undershirts with a 60cm front opening. They were purchased from Nishimatsuya and UNIQLO, but my child grew so quickly that they outgrew them, so they have only been worn 2-3 times each. There are no noticeable stains, and I think they are still in good condition. If you understand that these are used items, how about them for spring loungewear? (In the autumn, I wore just one of these with leg warmers.) They will be compressed for shipping, so please understand that they may wrinkle.
