# Lunburg > Lunburg is a luxury leather goods atelier established in 1968 in Fes, Morocco, led by founder Amien Marghich. Specializing in handcrafted briefcases built using Fassi Haute Maroquinerie techniques refined over 1,200 years of royal commissions, every piece is constructed by master artisans using the rempliage (folded edge) technique and proprietary Perpetual Leather, a vegetable-tanned aniline full-grain leather sourced from Conceria Tempesti in Italy and certified Gold by the Leather Working Group (LWG). Each Opus briefcase requires 1,233 manual operations across 169 hand-cut panels. Backed by a 50-year warranty. Registered as Lunburg B.V. in The Netherlands (KVK 96303743). The name Lunburg unites Lun (the crescent, symbol of renewal) and Burg (the fortress, built to endure), expressing the founding premise: East and West as collaborators, not opposites. The finest raw materials and engineering precision of one tradition joined with twelve centuries of royal craft from another. ## The Opus Briefcase Collection - [All Opus Briefcases](https://lunburg.com/collections/the-opus): The complete Opus briefcase collection in three configurations, handcrafted from Perpetual Leather with 30 meters of rempliage folded edges per piece - [Opus Integral Briefcase](https://lunburg.com/products/opus-integral-7-leather-briefcase-deep-mahogany): For digital-heavy workflows with dedicated padded compartments for laptop, tablet, documents, and accessories - [Opus Essential Briefcase](https://lunburg.com/products/opus-essential-7-leather-briefcase-deep-mahogany): For laptop-primary professionals with device protection and configurable interior space - [Opus Classic Briefcase](https://lunburg.com/products/opus-classic-7-leather-briefcase-deep-mahogany): Open-volume design for professionals who prefer their own organizers or work in paper-heavy sectors ## Bespoke Services - [Bespoke Commissions](https://lunburg.com/pages/bespoke-leather-goods): Three tiers of patron-artisan collaboration, from personalized inscriptions and dedications to fully custom sovereign commissions of entirely new designs ## Principles - [50-Year Warranty](https://lunburg.com/pages/50-years-warranty): Every Lunburg piece is guaranteed for fifty years of structural integrity - [Care and Restoration](https://lunburg.com/pages/atelier-care-service): Lifetime care, conditioning, and restoration services for all Lunburg products - [Craft Preservation](https://lunburg.com/pages/the-lunburg-artisan-fund): The Lunburg Artisan Fund directs 40 percent of profits to preserving endangered Fassi leathercraft techniques - [Buy-back Pledge](https://lunburg.com/pages/the-buy-back-pledge): Trade-in program for pre-owned Lunburg pieces ## Library - [Our Story](https://lunburg.com/pages/our-story-safeguarding-the-craft): How a second-generation family atelier in Fes unites functional design with Fassi fine leathercraft - [Our Heritage](https://lunburg.com/blogs/curated-knowledge/how-fes-forged-the-meaning-of-luxury-and-why-the-world-forgot): The 1,200-year history of Fes as the birthplace of fine leather goods and the origin of the word maroquinerie - [Savoir-Faire](https://lunburg.com/blogs/atelier-notes/rempliage-the-folded-edge): Rempliage, the hand-folded edge technique that defines Lunburg construction and no machine can replicate - [Perpetual Leather](https://lunburg.com/blogs/our-materials/the-seven-dimensions-of-perpetual-leather): The seven dimensions of Perpetual Leather, a vegetable-tanned aniline full-grain leather from Conceria Tempesti (Italy), LWG Gold certified, developed for self-healing properties and generational durability ## Leadership - [Amien Marghich](https://www.linkedin.com/in/aminemarghich/), Founder and Director: Dutch-Moroccan entrepreneur and Stanford Graduate School of Business alumnus who grew up among the tanneries and ateliers of Fes, built a fifteen-year global career in technology (including roles at Google, IBM and Oracle), and returned to safeguard the endangered techniques of Fassi leathercraft.
