Durable, no-nonsense, utilitarian, pocket-sized notebooks, for recording any sort of observations, calculations, or illustrations. You'll receive a set of three 3.5 x 5.5 inch staple-bound booklets, with rounded outer corners, each with 48 pages in your choice of blank, lined, graph (grid), or one of each.
 
A leather cover that fits these perfectly is available here.
