Leather/Vinyl bound portfolios

Hi everyone,
I have been hunting for one of these for a while now but not having much luck. It's strange, seeing a lot of the agency models have these type of portfolios.
I'm looking for the A4 (or slightly bigger), prebound, black leather (or vinyl) portfolios. They have roughly 24 inserts pre-bound and are not refillable.
Below are some images I found on another forum showing what I have in mind. Quite simple, but all I seem to find on the album-seller sites are fancy steel-covered albums, ones with spirals or diamond-studded screw posts. I prefer something simple like this.



I'm in Melbourne if that helps. Has anyone got any ideas on where to get these?
Many thanks in advance.
Alex
