Honestly, these tiny books have always seemed pricey to me, but it's hard to argue with quality and usefulness.  I always keep a stack on me for notes at job sites.  They fit perfectly in a product I purchased a while back from Amazon listed as "Italian Leather covers for your Pocket size Moleskine Cahier or Fields Notes Notebooks. Made in USA. (Color: Merlot)" by "Renaissance Art Leather", so much so that I was going to include a link here, but it seems they've vanished from Amazon.  Pity.
