Shimamura short-sleeved summer pajamas, 3-piece set (top and bottom) Includes both button-up and button-less (elastic neck) tops, and pants. Onigiri (rice ball) pattern, bento (lunch box) pattern, and wiener pattern. I bought these intending to have my son wear them, but he outgrew them while they were in storage. I bought these for my son who loves the "Bento no Uta" (Lunch Box Song) from "Okasan to Issho" (*^^*)
