- Perfect for textbooks, coffee table books, cookbooks & thick novels
- Makes reading hefty volumes easier on your hands
The Page Keeper is a clever little 3D printed office accessory that solves a surprisingly common problem: how to hold open a thick book without your thumb cramping up. Slip this ergonomic rest onto your thumb, and suddenly that 800-page novel or heavy coffee table book feels a lot lighter.
Inspired by a Japanese design spotted in the wild, this handy reading tool gives your thumb a comfortable platform to press against the page while you read. It's especially great for textbooks, cookbooks propped on the counter, or any tome where you're flipping back and forth and need a steady hand.
The design is elegantly simple, just enough surface area to distribute pressure without getting in the way of your reading experience. It's one of those "why didn't I think of that?" gadgets that book lovers and students will genuinely appreciate.

What it is made of

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
