JnK is another manufacturer of high end leather cases for Leica cameras and accessories located in Korea (see also their Arte di Mano collection). I had the chance to try one of the Arte di Mano cases in the Leica Store in Miami and it's one of the best cases I have ever seen. Of course the price is also very high - the case I tried was $390 (with embedded tripod mount). Some other models cost over $1000.
