Sun-Star Ukanmuri Clip - Clear

The Sun-Star Ukanmuri Book Clip is a hands-free page holder inspired by the Japanese kanji radical ukanmuri (宀), meaning "roof" or "crown." Its arched, clothes-hanger-like shape avoids the bulge of the book spine while securing pages on both the left and right sides at once — perfect for thick textbooks, cookbooks, reference guides, sheet music, and planners.

Opens up to 8 cm (about 3.15 in) with minimal effort. The arched form leaves the center of the page uncovered, so text and images stay fully visible while you read, cook, or study. Non-damaging grip protects book covers and pages, making it a reusable, eco-friendly alternative to sticky flags or dog-earing.

Winner of the Idea Award at the 2024 Japan Stationery Awards.
