This is the highly popular and immediately sold-out Shimamura x Hokaron Happy Bag! This listing is for the pajamas only (purchased last month). They are very warm and made of a soft, fluffy material. I purchased two sets, so I will be sending an unopened item. Size: M Color: Gray (Please note that there may be slight variations due to amateur measurements.) Please understand that this item has been stored at home, and kindly consider purchasing if you are comfortable with this. Please be aware that the product may be opened during packaging.
