Campus Lay-Flat Book Pen Case / KOKUYO

For planner and memo lovers: a pen case that opens flat like a notebook — so you never dig for a pen again.

"Where did that pen go?"
Those few seconds of rummaging through your pen case — it happens every day, and it adds up. This little case from KOKUYO's Campus series puts an end to it.

Opens a full 180° — flat like a notebook

Unzip it and the case lays completely flat, just like an open notebook. Everything inside is visible at a glance, so your hand goes straight to the pen you want — no digging, no guessing.

Everything stays neatly in its place

Inside, five open pockets plus a zippered pouch keep your tools sorted by item. The case holds around 18 pens, with room for sticky notes, memo pads, clips, and small scissors. Even fully loaded, it never turns into a jumble.

There's also a dedicated pocket that fits A6 notebooks and binders. Your pens and your memo pad travel as one set — so you're always ready to jot down an idea the moment it strikes.

Stacks on your planner — carry it in one hand

With no gusset, the case keeps a slim, flat profile that never gets bulky.

Its footprint is close to a B6 or A5 planner, so it stacks neatly on top for one-handed carrying — and slips easily into smaller bags, too.

Available in three colors

Choose from soft mint green, calm gray, or classic black. A perfect companion for journaling time, study sessions, and anyone who carries their favorite stationery everywhere.
