Tally Books are used in many industries such as oil fields, pipe lines, cattle ranches and all kinds of other professions. They are used to keep count and records of things and are specifically designed to be slender and tall so that they can fit in a pocket yet hold a lot of information. Our Tally Books are 3 3/8" wide and 7 7/8" Tall when closed. These make a great companion to our Tally Book Template.
