This page holder is designed to distribute the weight of book pages evenly, making it easier to hold a book open with just one hand. Ideal for improving comfort during reading and allowing for multitasking or increased productivity. It can be used to hold pages open with one hand, or folded and placed between pages as a bookmark, making it a flexible tool for professionals, students, and readers who value practicality, portability, and thoughtful design in everyday use. Initially designed to be made of wood, the page holder was reimagined in 3D-printed ASA (Acrylonitrile Styrene Acrylate) to better support its modular, interlocking components. The material is lighter, water- and UV-resistant, making it ideal for both indoor and outdoor use. It also includes a small pouch for easy storage and transport. Note: The PRACTICAL model is intended for everyday books and general use. For particularly large or heavy volumes, a separate model (COMFORT BASHI) is currently in development to ensure optimal performance across all reading formats.
