What is Triangle Notebook?
"Triangle Notebook is a subversive approach to the traditional rectangular notebook. Its triangular shape opens up, slyly, to reveal perfectly square ruled pages. Triangle Notebook's shape is easy to carry around and its compact size is perfect for doodles, sketches, or writing your next novel. You decide."
