This refill for the regular size Traveler's Notebook measures 11cm x 21cm (approximately 4.33in x 8.25in), and contains 12 sheets (24 pages) of white thick blank paper.
This notebook refill is perfect for watercolors because it is water-resistant. Watercolor Paper that is a little thicker and more textured than "012 Sketch Paper" is also perfect for pencil and pen sketches or collages of photos and tickets. The pages are perforated so after you draw on them, the regular size can be sent as a picture postcard, while the passport size is ideal for a hand-drawn card with a message.
