No.541 Chicago Shell Briefcase | Horween® Tumbled Black (x6)

NEW October 2026 Release | Only x6 Available
Built and In-Stock Now

The No.541 is an exclusive and very limited edition briefcase made in micro-batch quantities. The original design was inspired from the classic 80’s style attaché hard cases. The No.541 is our first and only briefcase made entirely from genuine Horween® Shell Cordovan and Horsehide Strip leather. Introduced in 2026, the No.541 delivers the functionality of an executive attache with modern styling, premium leather and materials, 100% tanned and built in USA. 

The No.541 is made entirely from Horween® horsehide leather. The front and back faces are each cut from an entire Horween® Shell along with the top handle wrap and all four D-ring holders, hangtag and a matching luggage tag. The bottom, side and top gusset panels are made from Horween® horsehide strips, the section of the horsehide that sits just above the "Shell". 
Horween® Shell Cordovan (Horse Hindquarter or Rump)is one of the most sought after and expensive leathers in the world, for a reason. The glass-like shine and extreme durability is ideal for small leather-goods, cases, folios & wallets. There is really no other comparable leather in the world. Artisanal tanned in Chicago for more than a century, genuine Horween® Shell Cordovan is in a class of it's own. 

THE DESIGN | An Organized Semi-Hard Case
Our most structured men's semi-hard briefcase built with a structured body and a top carry handle reinforced with a steel bar for structure and weight support. The interior is fully lined with premium 10oz. herringbone cotton lining imported from Japan. The fabric is made by Yoshiwa Millls in Japan and is a shuttle loom woven fabric, for supreme quality, durability and texture. The top handle is comfortable in the hand and the steel bar supports more weight than is needed. The No.541 is our only briefcase that uses a hand-polished, #8 Excella® brass zipper. These are symmetrical, highly polished and true "luxury quality" zippers that are made in Japan. The two double brass pullers extend almost completely around the face, making access to the interior easier than the typical top-zip briefcases. The back panel has a 11” brass zipper pocket that is lined with genuine suede and a rear trolly strap to attach to rolling luggage. 
Includes a double-layered 1" shoulder strap also made from Horween® horsehide, along with the adjustable snap-on shoulder pad. 

Genuine Horween® Tumbled & Marbled Shell Cordovan 
These Limited Edition cases are made from rare and very limited "Tumbled & Marbled Shell Cordovan" leathers. Each and every shell is unique with it's own color pattern, no two marbled shells are exactly alike. These were hand-selected at the Horween® tannery in May 2026 and in-stock now. 
This October 2026 release is made from Tumbled & Marbled Shells. The difference between Horween® standard Shell Cordovan and the Tumbled Shell Cordovan is two-fold. In the tumbled shells you will see a more matte finish where the traditional shell is quite polished and glossy. The second difference is the "temper" or stiffness of the leather. The tumbled shell cordovan is softer with a little less structure but with equal thickness and durability. Marbled Shell Cordovan in general will require less maintenance to keep it's original appearance and look. Both versions have their place and are equally special leathers, it simply comes down to personal preference.
