The Hobonichi Techo uses 12 soft colors across the book. The TSUKI no IRO stationery series incorporates these colors into simple designs. These stickers help you flip straight to the right page in your Hobonichi Techo. A set of two sheets: one with numbers 1 to 12, and one plain. Made from sturdy, firm PET material that’s easy to flip. The compact size doesn’t stick out too much from the edge of the techo, and the matte texture gives it an elegant look.
