Using precise laser cutting lines to outline sharp arrow contours between cardboard sheets is not only a practical form of paper clip, but also a gentle guide for reading. Gently sandwiched between the pages, the colorful cardboard adds a bright touch of color to the book, and the next time you open it, you can easily find the starting point of the story to continue exploring. Each cut is clean and sharp, with smooth edges that do not damage the paper, allowing for a perfect coexistence of reading ceremony and practicality.
