The case is smaller than I thought, which was a pleasant surprise to me. When closed it is slightly larger than a Moleskine Pocket Notebook.
The "Saddle" color looked like a dark brown on their website, but it is reddish brown. It reminds me of a leather football. The leather is their standard material, soft and nicely stitched.

It looks like it's about the right size for Pelikan M400 size pens.

From left, Pelikan M400, two Sailor Sapporo Minis, Pelikan M320.
My decimo looks almost like a tight fit lengthwise.

The pen loop has elastic on either sides, allowing it to hold small pens like Pelikan M300 series to larger pens. I could shove Sapporo Mini's cap down in it but I am afraid I will stretch out the elastic.

I think they are using the same format/outside cover as their PDA case and Circa Zip Folio, probably a smart move for them.
I debated whether to get Pen Parapet or this, but I like the convenience of having 3x5 cards handy.
Over all I am very satisfied with the case, especially at the price I paid
