It is great paper. It's a Cachet Earthbound sketch book and they can be hard to find in stores, but you can order them online.

I love this for dry media drawing and also pen and ink, but it's lightweight and doesn't take ink washes or other wet media; it'll buckle badly. When I want brown paper that will stand up to anything, I have to use Rives BFK Tan, which is a thick velvety printmaking paper that I love love LOVE.
