World-renowned German product designer Dieter Rams has teamed up with TSATSAS to create an exclusive leather handbag.

The 931 bag is available in two colors, black and concrete, both with a blue leather lining and silver details. Handcrafted in Germany, the outer is calf, while the lining is lamb nappa. Retailing for €900 ($1019), the handbag is available from TSATSAS.

The handbag was originally designed as a one-off by Rams in 1963 for his wife, but it was never released — until now. The piece is instantly recognizable as Rams' work, adhering to his ethos of "good design is as little design as possible."

Dieter Rams is one of the world's most well-known designers, and is famous for his "10 principles for good design."
