Hermes Birkin?

I agree with shoes that it's a 35cm. Here's a stupid trick(I'm bored at work)::wacko: Strictly looking at the base and not where it bulges on the sides- a 30 cm would be from the end of my elbow to the base of my thumb and a 35 would be to the end of my middle knuckles. I know we all have different length arms and fingers but you can kind of get a ballpark idea looking at a handbag carried on the forarm like she is carrying it.
