I received this as a gift (that I picked, so I'm certain it's from this listing), I'm not sure what makes my Strawberry Wolf a B-Grade. I checked her over and she looks exactly as I would expect a plush to look. Any flaws I found, like a loose thread or tiny piece of plastic from under an embroidery, weren't serious enough to detract from the aesthetic or value of the plush. Definitely a great deal.
For a b-grade plush, the strawberry wolf I got was in very good condition. Highly recommend if you want to save some money.
