This set of 3 memo pads is designed to fit perfectly into the back pocket or inside of an A6 Hobonichi Techo Planner / Original cover. Pages are made with the same thin and strong Tomoe River paper from the planner book. The 3.7 mm plain graph paper allows ample writing space, with perforations on each sheet to make it easy to rip out for those important notes to pass on. It's also useful as a notebook around town. The page size is slightly smaller than that of the planner, which makes it easy to pull out a sheet and paste it onto one of your planner pages. The memo pads come in three fun colors.
