Yuru Log by Midori is a fun series of notebooks and stickers allowing you to reflect your own style.
 
Featuring cute monsters and ghosts in black with copper foil details, these stickers are intended to camouflage embarrassing or unappealing mistakes you've made in your planner or journal. The high-quality washi paper is removable and has a special coating so you can write directly on it with water-based pens.
