Color: Yellow系 (Yellow-based) Season: Autumn/Winter Stains, tears, odors, etc.: None Made of polyester, acrylic, wool, and polyurethane. I bought it intending to wear it, but missed the opportunity, and it was stored new in a bag in a dark place. It's similar to the "Jatsukureba" Minato-kun cardigan. I took it out of the bag to take photos.
