It can be found here:
Plumb Stack Book or here on Amazon (click picture to see on Amazon):
It is $20.00 and has 244 pages. 8 x 6.25 Lays flat, not lined. Pages are cream colored with deckled edges.
I only have a Pilot Metropolitan Fine Nib, but it did not show through the pages or feather. I'm guessing that the calligraphy pens would be similar.
I like lined books, but figure I can either line it myself or put a guide sheet under it with 7mm lines.
Again, I am new at this and cannot really give you any more information than that. Thought it a good deal for the size, number of pages, page quality. A local paper supply store had them, so I gave it a try.
I was looking for something as a daily journal for thoughts and to help improve my cursive hand writing.
