The Hobonichi Techo Original Avec Book splits the standard A6 size Hobonichi Techo Original into two 6-month books. The Avec July-December Book contains the last six months of the year with half the daily pages as the standard edition but all the informational pages*, meaning the weight and thickness of the book are cut in half, making it light and portable for carrying around. (*Please note that the Avec Jul-Dec Book does not contain any blank memo pages in the back.) The Avec fits the same covers as the standard full-year techo, but because it is slim, you can also store it inside the cover alongside the Hobonichi Plain Notebook or other slim notebooks.
