And the back cover is stiff enough; some of the cheap notebooks are so floppy you can only use them on a solid desk or table.

Sturdy cover on the front and back.

Strong, thick cover which I like, and the sleeves are a bonus.

The cover is very sturdy and unlike many paper covers doesn't apper that it will come off in a backpack.

Nice sturdy plastic cover, 30 more sheets

Weak cover

Nice quality cover but the paper is a bit thin.

Graph paper and durable outer covers

The front and back cover was so flimsy to this and the paper looked all crushed and warped as though it had water damage.

The paper is nice and thick(as far as notebook paper goes) and the cover is sturdy.

the front and back covers are good quality and don't rip along the spiral binding, even after repeated use.

I thought there would be like 10 pages of graph and a cheap cover

Paper quality is great, and the cover is sturdy

I think that the cover is very durable

I like the plastic covers.

The cover notes that it is bleed-proof to normal usage, and while I respect that heavier-ink pens are outside that description, you can visibly see your writing from the other side of the page, even if it hasn't technically bled through

Great sturdy cover and graph ruled paper
