Panther CR books are generally used by high school students. The books consists of multiples of 40pages. They are known as CR1, CR2, etc, which would be 1 x40= 40pages. Panther CR books up to pages 120 are wire stitched while the 160 and bigger books are sewn, and are printed on 60gsm papers. As these are designed for daily use of students and general use, they are priced at a very economical price. We used a design that could be appreciated by many.
