Zequenz, a line of notebooks that I bought from my local bookstore. It is probably the best notebook I have ever used.
It not that cheap to begin with. Ever since I started on my Final Year Project, the things I do in my lab and the experiments I perform on a daily basis, requires me to keep a log of all the things I do. I came across Zequenz, a line of leather bound notebooks that is super versatile and hardy. You can roll it, bend it, and the pages will not tear or fall off the seams. The best part for me is the ability to spread the pages out flat on the table, no matter which page of the notebook you are at, allowing you to write comfortably. Unlike notebooks with metal coils holding the notebook together, Zequenz allows you to write without any obstructions in the middle of the notebook.
These notebooks will definitely be my choice of notebooks. I will definitely get more of those and bring it wherever I go. It would be perfect for me to write my thoughts down on an old traditional medium now that I have my notebook of choice.
