A bag with roots in the postal system. The large main compartment holds file folders with up to 8 cm in width or – in the separate felt pocket – notebooks with up to 15-inch monitors. The other pocket is suited for individual documents in A4 format.
Additionally, there is a pocket for a mobile phone, two pen loops and a small pocket with zipper. The bag is made from pit-tanned cowhide that is comparatively soft and has a distinctive hide structure.
Despite its size, the front and back are made of one single piece of leather, increasing the durability of the briefcase, since there are no seams at the bottom. The carrying handle is made of four layers of processed full cowhide leather; a steel rail runs over the entire bag giving it stability.
The adjustable shoulder strap is fastened with two oval rings on the back, allowing the bag to hang straight and close to the body. The belt can be easily unclipped and removed, if desired.

Since the 1980s, the leather manufacturer Ackermann has stood for handcrafted and resource-conserving production. Ackermann uses exclusively high-quality leathers tanned in German or European tanneries with minerals, vegetable substances or ingredients of animal origin (for example, fish oil for tanning deerskin). Beate Sedlacek and Karl-Henning Hohmann create the designs – the Bauhaus says hello – primarily based on an idea of functionality while reflecting on the characteristics of the respective leather and its surface. The resulting design is timeless, dispenses with superfluous details and features a clear cut in which every seam has its functional artisanal justification. Therefore, the leather can show all its strengths, including its visual and haptic qualities. Experienced sewists implement the designs in the best bag-making manner. Ackermann manufactures most of the articles at its headquarters in Lüneburg and has certain product lines made in a Czech partner company.
