I don't know the manufacturer because there's no tag. I've borrowed the name "Big Mac." I bought this at a used clothing store a few years ago. The tag was missing from the time I bought it, so I can't identify the manufacturer. However, it's a thick flannel shirt with gussets. I'm selling it because I have too many flannel shirts and I'm decluttering. Condition: No tears or stains. Size: Estimated L Length 73cm, Width 56cm, Shoulder Width 44cm, Sleeve Length 63cm Since the manufacturer is unknown, I've priced it affordably. Please purchase only if you understand that this is used clothing.
