This is a set of three pajamas from Nishimatsuya. All are 100% cotton. They were originally size 100 tops and bottoms, but I discarded one top, so I'm pairing it with a size 110 dinosaur-patterned top that was worn around the same time. They were worn for one season. There is some fading from washing, and the pants have small pills, but they are still wearable. They were used at home, not at daycare, so there are no name tags. Thank you.
