Hope for the planet?

I LOVE their products, sturdy, beautifully and imaginatively designed and made, great customer service and they employ the differently-abled. I purchased: 5 hardcover notebooks, 2 softcover notebooks, a mega-mug (works for soup as well as giant coffee), and 3 of the cards. I am delighted with everything and have pointed several scientist friends to the site.

Beautiful and useful - my soft spot!

I love that CS demonstrates the opacity of their paper, much appreciated. I am using this as a bullet journal. I love the hard cover as well as the design. It feels sturdy, which I need. So pleased that I stumbled on this website!
