I also have the same concern as hihilor. Hence, I bought an Azap H long wallet (inside - all leather, the design of silk in and Azap is the same, but the price of Azap around $24,000).
H silk in and Azap - 外表雖然平凡,但內裏的design is very good especially if you have many credit cards to place in wallet. All the stuff inside wallet could be well-organised.
