This is a set of long-sleeved undershirts. All were purchased at Nishimatsuya and are 100% cotton. The light blue undershirt was used for about two seasons and has a name written on the tag. I will black it out before shipping. The other three were used for only one season. The bear-patterned one has a name written on the name tag, so I will cut off the tag (the quality label will remain). The other two were used at home and have no names written on them. Would these be suitable for daycare?
