This is a collaboration item between Thomas the Tank Engine and the Oigawa Railway, and it's a cute and valuable item! It's black, so dirt doesn't stand out. The size 2A is, according to the official website, for 75-85 cm (up to 2 years old). My child wore it from 1.5 to 2 years old. There are no noticeable stains or frays. The fabric is sturdy, so the neckline hasn't stretched and is in good condition. *Upon close inspection, there is a 5mm stain near the left collarbone. It's barely noticeable because it's on black fabric. Please understand that this is a used item.
