These notes are so fun to use. I got the pink version. Additional information: the notes are opaque. (I thought they could be the clear see through type from the photos, so just a heads up.) The notes are about 2-2.5 cm in diameter, so they're pretty small, but perfect for using in planners, which seems to be the intended purpose if the packaging is anything to go by. I think they would go great with the "Sumikko Gurashi B6 Size Weekly Planner," which I also bought at the same time as these sticky notes.
