Nice to journal & track...
Recently discovered journaling so love these books to help me track things - like the grid lines and quality of paper.. Havent used with a fountain pen so cant attest to bleed thru but ballpoints and zebras are fine.

Cheap, good quality, useful notebook
I am an HGV driver and use these to keep notes regarding my shift times, break times, the vehicles I have driven and anything else that I might want to refer to later as a record of my work.I like that these are well made, yet reasonably priced. The pages are bound well into the book, which has a unique appearance about it! The paper is also of good quality considering it is a notebook; it stands up to me writing on both sides and then using a Stabilo Boss highlighter to highlight parts of my notes, without the highlighter leaking through too much to the other side of the page.

Great quality notebook
These little notebooks are great! A little expensive compared to some others but the quality is excellent! I write in it with a fountain pen and there is no bleeding so the paper is of a good thickness. I keep it in a leather cover which gives it extra protection, there are a variety of different measurements etc printed on the cover of this notebook, a great design and I recommend them.

Meh!
I usually use Molskine field notes but they are expensive so I bought these. They are not as good quality and they don’t have as many pages, and no perforated rip out pages. They do the job though.
