Anpanman Pajamas - Color: Yellow Check - Design: Anime Character Embroidery - Size: 100cm - Material: Flannel Thank you for viewing. It says 100% cotton. I think these pajamas will be useful from the end of winter to spring. The buttons are Anpanman, Baikinman, Melonpanna-chan, and Dokin-chan, which is very cute. The pants have "right" and "left" written on them in English, which is also good for learning English. I think the condition of the elastic on the pants is good. There is some pilling/fuzzing, so please understand that this is a used item.
