Great inexpensive notebook.
They saved on cost with the plastic cover and stapled spine, but made up for it with inner cover folders and keeping with 90g paper.
Using a 3.4mm Pilot Parallel there’s bleeding and ghosting. The bleeding is not an issue due to the back plastic folder that works great as a paper guard.
I still prefer my Clairefontaine Age Bag notebook for daily logs, and my coveted Rhonda notebooks for important notes. When it comes to practising calligraphy, this Koverbook is my new go-to.
