This set of three memo pads is designed to fit perfectly into the back pocket or inside of a Hobonichi Planner cover. Pages are made with Woodfree Paper and thin enough so it won't add bulk to your cover. The 3.7-millimeter 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.
