I have had it professionally authenticated and at first it was told as authentic, but when I noticed the stitches, showed photo and asked again, it was told as nonauthentic. I can believe there may be manufacturing faults, that's why I am asking to share other opinions.Where did you get it? Was it authenticated if you bought it preloved and not directly from a Bal retailer? If you're concerned about it being fake, you'll want to get an authentication service to check it out.
