ステーショナリー大好き テーマ Hobonichi Cousin ウィークリーキット（3枚セット）

The vinyl sheets are genuinely writable—my ballpoint glides over them without a single smudge, and the set of three means I’ve got backups for when I mess up a week. They fit perfectly in my cousin planner and make Sunday planning feel almost too easy.

I was a little worried gel pens would smear, but everything dries instantly on this vinyl—no ghosting on the next page. The three-piece set covers my weekly needs without adding extra weight to the planner.

The vinyl is thin enough to not add bulk to my Cousin, but still sturdy enough to stay flat on the page. I love that the sections are already sized for the weekly spread, saving me from drawing lines myself.
