The notebook is sewn-bound, hence being able to opened completely flat. There is a fabric covered on outer spine, combined with the cardboard cover, makes the notebook somewhat wear-proof.
The paper used is bright bleached white with neon-yellow (looks
darker here due to sunset) grid that are not too noticeable but works
well enough as guide line. The surface is slightly textured but overall
quite smooth (not the slippery type) enough to write on. It's pretty
fountain pen compatible, allowing some shading and never causes
feathering or bleeding...Basically, it's the same type of paper as note
card.
Given individual sheets are so thick, the notebook achieve the slim figure simply by having very few pages (24 sheets/48 pages). Since it's a bit of a hassle to carry a heavy (compared to the capacity) notebook with few pages, it's not handy as a note jotter to carry around. Instead, I use it for more permanent writing: Hand copying down pattern that I would knit over and over again (I have finished 5 of the same hat since summer!). It could work as a sketch book, even though the yellow grid kind of gets in the way.
Overall: For 3 dollars, it still seems like a bit of a rip-off. (I could get a whole box of on-clearanced Pukka bagged tea at TJ Maxx!).
