how many sheets in this notebook?

80 sheets. It's thick, coated paper (great for fountain pens), so you should be able to write on both the front and back sides of each sheet with no bleed-through.

What is the height of the rules? Is it 7mm or 8mm?

I measure rules at precisely 7mm.

Wondering how is everyone using it

I used other notebooks for notes at work. I bought this specific one for tracking Rummy scores between my wife and I.

How fountain pen friendly is it when compared to a moleskine notebook?

Very fountainpen friendly! I primarily use a lot of steel flex pens that not only deposit a lot of ink but also carves pretty heavily into the page. This paper works very well in minimal to no bleeding and ghosting. Absorbs ink well and showcases a decent amount of sheen/shading
