This planner sticker sheet brings a playful, slightly unexpected mood to everyday planning. Illustrated by Shinzi Katoh, the designs balance whimsy with restraint, expressive without overwhelming the page.
The “Mystery” theme works well for planners, journals, calendars, and small visual accents in letters or notebooks. These are stickers you use sparingly but regularly, to mark a moment, add a hint of story, or break the rhythm of plain pages.
The sheet format makes it easy to see all designs at once and choose intuitively. They pair nicely with both minimalist planners and more decorated journal spreads.
