These Composition Notebooks from Maruman are thin, sturdy, and perfect for coordinating different subjects. They measure 10.1 x 7.1 inches and are great for anyone who is looking for a compact and thin lined notebook for writing. In a typical letter sized spiral notebook you might find 33 college ruled lines. However, this notebook is much more compact (more than an inch shorter in both width and length) but has 31 lines so you will still be able to fit a ton of stuff in. Goes very well with a Hi-Tec-C 5 Pen Gift Set!
