I use these for gouache painting. Love the thickness and quality of the paper. I like that it is a visual diary with 300gsm paper. It can be hard to find diary/sketchbooks that are 300gsm. I love the binder, ie how I can fold the front cover out of the way. I also like that I can remove the paper easily if I want to frame or scan the image. The books are easy to store or take with me to places where I have time to paint. I use them for Plein air painting, or sitting in my car etc. I've even sat in Maccas and started a painting.
