I purchased this new at a store, but I don't think I'll have a chance to wear it, so I'm putting it up for sale. It's a thin sweatshirt, so I think you can wear it for a long time, in spring, autumn, and winter. KOMACHI design sweatshirt, size 110, a blend of polyester and cotton. - Brand: TRAIN GARAGE - Size: 110 - Material: 65% polyester, 35% cotton - Design: KOMACHI print - Color: White/Red Shinkansen Komachi Hayabusa Plarail Train Car Tomica Boys
