Sunstar Ukanmuri Petit Clip

Meet the compact version of the award-winning Japanese stationery sensation. Inspired by the shape of the Japanese "Ukanmuri" kanji character (this ingeniously designed page holder is a game-changer for students, planners, journalers, and readers alike.

While standard clips press directly on a book's center spine—causing page damage and blocked text—the Ukanmuri Petit features an innovative arched design that completely straddles the spine. It securely locks your pages open from the left and right simultaneously, keeping your notes completely flat and hands-free without hiding a single word.

At 25% smaller than the original, the Petit edition is specifically optimized to fit perfectly on compact notebooks, pocket journals, and A6 planners, while slipping effortlessly into your pencil pouch.

Why It’s a Must-Have for Your Desk

• Spine-Safe Arched Design: The unique crown shape completely bypasses the fragile center spine of your books. It prevents creasing, cracking, and damage, making it perfect for expensive textbooks and treasured journals.
• Maximum Text Visibility: By clipping the outer edges rather than burying itself in the middle of the book, it leaves the center gutter open so you can read and write right up to the margins without moving the clip.
• Pocket-Sized Portability: Engineered for life on the go, the Petit version is incredibly lightweight (just 20g) and compact, matching the footprint of small planners without weighing down your bag.
• Strong Yet Gentle Grip: Don't let its mini size fool you. It boasts a powerful internal spring that can clamp open up to 3cm (over 1 inch) of paper—plenty of strength to tame thick paperbacks or up to 4 stacked journal inserts.
• Ergonomic, Low-Effort Open: The wide-winged shape acts as a lever, allowing you to open the strong clamp with minimal hand pressure.

Perfect for: 

• Journaling & Planning: Keeps your Traveler’s Notebook, Hobonichi Techo, or bullet journal open flat for effortless decorating and writing.
• Studying & Desk Work: Holds open reference books or study guides next to your keyboard so you can type comfortably with both hands.
• Cooking & Baking: Keeps recipe books wide open on the counter while keeping your sticky hands far away from the pages.
