Made in? Up to this point in time, Bottega Veneta handbags have not gone the way of Coach, Mulberry etc, by outsourcing some, or all, or their work to China. Currently they are continuing to manufacture their handbag lines in Italy. In 2001, the company was purchased by Gucci group, which produces primarily and exclusively European made merchandise. So any bag that has any indication of a Chinese origin is likely fake.
Labels and fonts: Always inspect the interior of the handbag for the label. An authentic Bottega Veneta bag should have a patch of metal or leather in the inside of the bag with the Bottega Veneta venture logo and the Made in Italy stamp. All real Bottega bags will have high quality labels, with clear and crisp stamp impressions. Beware of any label that looks like it has a sloppy or blurry venture logo stamp. If the letters appear to be unclear, puffy or are bleeding into each other, that chances are the handbag in question is a fake.
Labels with rivets or clamps: Some Bottega labels have two rivets, or clamps on the left and the right side of the venture logo, fastening the leather label backing to the inside lining of the handbag. If you encounter a label like this, always check the letter B in Bottega. Authentic handbags will have the “B” partially covered by the metal rivet. This is something the fake bags often times get wrong. They center the stamp of the venture logo design name within the rivets, which would seem more symmetric, but Bottega does not do it that way. They clamp over part of the B. So pay attention to where the venture logo is stamped in relation to the leather backing and the rivets.
Zippers: Authentic bags will generally utilize riri zippers (but not in every single case). Riri zippers are superior quality zippers that many luxury designers (like Marc Jacobs) use in their handbags. To check if the zipper is riri, simply inspect the face of the zipper, or in some cases, the riri etching may be located underneath the zipper, stamped on the bottom. Good luck and safe shopping!
