Product Description
Sunstar UKANMURI Award-Winning Reading & Document Clip
Elevate your reading and organizational experience with the Sunstar UKANMURI Clip, a triple-award-winning stationery essential designed for modern students, professionals, and book lovers. Named after the Japanese "Ukanmuri" (roof) radical, this clip features a revolutionary arched design that solves the most common frustration with traditional binders: obscured text. Whether you are tackling a thick textbook, following a complex recipe, or organizing office bills, this clip ensures your pages stay perfectly flat and your view remains completely unobstructed.
Key Benefits
Unobstructed Visibility:** The unique "roof-shaped" arch is specifically engineered to span across the top of your pages, ensuring the clip never blocks text or images, making it the ultimate tool for focused reading and study.
Triple-Award Excellence:** Proudly recognized as a top-tier stationery innovation, this clip won the prestigious 2024 Stationery Shop Award (文房具屋大赏), the 2024 Navi Stationery Selection, and the Bun2 Award.
Effortless High-Capacity Grip:** Despite its lightweight feel, the clip opens wide—up to 8cm—with minimal pressure. It is designed to be easily operated by children or individuals with weaker hand strength while remaining strong enough to hold thick books open.
Advanced Non-Slip Technology:** The interior of the clip features dual mountain-shaped tabs and extended legs that provide a secure, two-point contact system. This ensures a firm grip on paper without slipping or damaging the page.
Rounded Ergonomic Design:** The sleek, rounded edges provide a comfortable tactile experience and prevent the clip from snagging on your bag or scratching your desk surface.

How to Use
1. Gently squeeze the top of the clip to open the jaws. The wide-mouth design allows for easy attachment even to thick volumes.
2. Position the clip over the center or edges of your book or document stack.
3. Release the clip to allow the two-point contact system to lock the pages in place.
4. For hands-free reading, use the clip at the top center of a book to keep it from snapping shut while you take notes or type.
Care & Safety
Store in a cool, dry environment away from direct sunlight to preserve the plastic's color and flexibility.
Do not force the clip to open beyond its 8cm capacity to avoid damaging the internal spring mechanism.
Keep away from high-heat sources, as extreme temperatures may warp the plastic frame.
