Fun to Play in the Dark
I was intrigued by the black-paper notebooks and suggested metallic pens. As an artist, I've always loved the way things look on black paper, and I thought it was a great idea to have a whole notebook full to sketch pictures and take notes. It makes me happy just to open the pages and play.

I loved the colors.
Rugged but beautiful
I absolutely adore my Cognitive Surplus canvas tote bags. I use them for groceries and they are great for cans and jars that some other multiuse bags don't handle. They also work for toting necessities when going on an adventure to the beach or mountains.
