The Ukanmuri Clip is a viral, award-winning Japanese stationery tool created by Sun-Star Stationery. It is specifically designed to hold books, textbooks, and planners wide open entirely hands-free.

Key Features

• The “Ukanmuri” Shape: The name comes from the Japanese kanji radical “” (ukanmuri), which looks like a little roof. The arched shape is functional; it intentionally straddles the center spine of your book so it never covers up text or text layout.
• Spine-Safe Clamping: By gripping the outer margins rather than pinching the middle spine, it safely holds thick books open without breaking the binding or crumpling pages.
• No Creases or Dents: The clip’s tension springs are calibrated perfectlystrong enough to keep heavy textbooks flat, yet gentle enough to leave no physical marks or indents on the paper
