What it does
- Measure millimeters right on your bookmark so you always have a ruler within reach
- Built-in pen loop holds your pen in place, so it stays with your book and never gets lost

- Keeps your page marked and your pen ready, so you stay organized without extra desk clutter
Stop fumbling for a ruler and losing your pen between pages. This bookmark does three jobs at once: it marks your place, measures millimeters, and holds your pen secure.
You get a flat bookmark with a working ruler printed right into the design. A circular tool lets you draw perfect circles for math projects, sketches, or technical drawings. The pen loop wraps around your book, so your writing tool stays exactly where you need it. Teachers and students love this for math class and project work.
Made to order just for you with 3D printing, this bookmark is built to last through a full school year or work project.
