Slide Collection is a minimalist design created by Japan-based designer Nendo. Hiroan, in Tokyo’s Asakusa district, is one of Japan’s oldest small leather goods workshops, with origins dating back to 1906. Hiroan’s unique ‘betahari’ method consists of layering two pieces of leather, tanned to 0.5 mm, across the grain, creating leather that’s extremely thin, tough and supple. The sewn edges are ordinarily finished with several layers of dye, but Hiroan polishes its leathers repeatedly after staining them for a distinctive gloss and sharp impression at the edges.
