Advanced N2-B Field DuraCover Notebook, 5.5 x 8.5 in (14 x 21.5 cm), 136 Pages, Gray Saturated Weave, Permanent Bound, 70lb Heavyweight Paper (1-Pack, Grid)

I use this type of notebook for regular writing and saving ideas because it's quality is better than most writing notebooks since it's designed for laboratory work.

I have tried a number of pocket sized notebooks for work and this is one of the best. It is very durable, ink doesn't bleed through the pages and the gridding is sized well for making hand sketches. Very happy with this product!!

It's is an engineering note book with a hard cover. Open the page and write, close the book when complete.

I love these books. I have used them for years as my go to daily notebook. The paper quality is great. I use fountain pens, ball points, and pencils in this book and not a single one has bled through. I find it too small to be a lab notebook, but for a daily planner or something similar it is great.

outstanding lab notebook....very reliable.....bought another to prep for the current running out. Love the numbered pages and number contents pages for tracking. Center binding glue lifted a bit (not surprising since it lays flat) but the side cover pages are holding firm. Cover fabric appeared porous, so I saturated it with Scotchguard before use. Very happy with the quality.

Should be call the NormalCover Field Notebook. There is nothing Durable about it really. It is a nice size however and I like that it has the page marker.

Use it nearly every day. Good hard bound, thicker pages that take ink and pencil well without smudging. Like the grid size as it's the closest to E2 grid which I prefer for full size use. This size is great for conferences and business meetings where desk space is limited (airplanes as well).

I use these as a cheaper alternative to Moleskine, for a day planner.Pretty sturdy, and a "wet" pen won't bleed through.
