Instantly eye-catching for all the right reasons, our No. 3 premium leather messenger briefcase showcases beautifully mature Italian craftsmanship and timelessly modern design.

All that without compromising on functionality. The robust design makes the No. 3 a reliable daily companion for a modern man. Ideally suited for business meetings and everyday work life, the No. 3 carries all your essentials protected and well-organized. A sleeve pocket with a fastening makes carrying a laptop up to 13” easy. The interior is lined with high-quality cotton canvas and there's a convenient zipped back pocket. But it's the detailing that truly makes the No. 3 stand out — not only does it have a two-strap and a lock-and-key closure, it also has a well-constructed secure leather strap on the back allowing you to fit and attach the No. 3 to a carry-on suitcase when on a business trip. The briefcase can be carried using the well-made top handle or the adjustable shoulder strap. Note the beautiful stitching that accentuates the form of the briefcase in all three color designs — black, brown, and tan.

We offer product personalization—embossing and engraving—for most of our leather accessories.

Add initials, names, dates, logos, phrases, or personal messages to create a truly thoughtful and one of a kind gift of sentimental value that can be cherished for years to come.

You’ll find personalization options on the product page of your chosen item. Select embossing or laser engraving before checkout, and we’ll take care of the rest.

Care & Packaging

We recommend treating your leather accessory once a month with our Premium Leather Cream. First, remove any dirt or dust from the leather with a cloth. Then apply a thin and even layer of the cream on dry and clean leather with a cotton cloth in circular movements. Allow to dry and then polish.

When ordering from us, you’ll receive everything ready to be gifted. Our bags come with a handmade cotton dust bag. Please use it when storing the bag to help the leather remain in good condition and develop a rich patina over time.Additionally, all smaller items such as wallets and belts will arrive beautifully wrapped in tissue paper, a gift box, and a gift bag.


We offer free worldwide express shipping on all orders over $500.

Von Baer products are crafted using premium vegetable-tanned Italian leather. Because we believe in the importance of sustainability, each of our product comes with a certificate of leather origin. The trademark Pelle Conciata al Vegetale in Toscana (Tuscan Vegetable-Tanned Leather) guarantees the quality and origin of the leather. It encompasses not just the material itself but also how it has been treated.


It is not without reason that Italy is known as the land of true artisans. All our products are made in Florence, Italy in family-owned studios, where the tradition of leather craftsmanship has been passed down generations. Believing that our customers deserve the best and showing our appreciation for this masterful heritage craft, we are ready to pay honest production prices for the high-quality work being put into each product.


We ensure that all our products are beautiful inside and out. We use natural thick and robust Italian cotton canvas lining. Unlike synthetic materials, it is sustainable and pleasant to touch. Moreover, the cotton lining is long-lasting thanks to the well-known Italian grasp of impeccable textile manufacturing. Due to this, an ordinary fabric like cotton is turned into something that will serve well to those who expect the highest quality.


Your product is only as good as its weakest link. You don’t want to throw away your bag after a couple of months of use simply because the zipper didn’t hold up. That’s why we only use the renowned YKK zippers for our products.


When choosing Von Baer products, you can be sure that you’re not only getting something stylish and high quality but are also supporting a sustainable business and traditional craftsmanship. We do our business in a way that supports local communities and does not harm the planet.
