Zeta Sketchbook 8.25 x 11.75in (A4) Hardbound 270gsm - Natural White Smooth

I've used this for the first time today and I'm very pleased with how it's handled both watercolour and pen. There is some buckling, but not enough to be an issue for me because of its versatility overall. I doubt I would use both sides of the page, though, which is always something to consider. I bought it because I am doing an online art course which tackles a variety of media and, having read reviews of this brand, I felt confident the paper would be capable of handling them all, which means I can have all the assignments together in one book.
