Design Your Own Bookmark

With our sustainable magnifying glass bookmark, you’ll have a clear view: You can use it to leisurely explore the details of our GRIN lenses. The best part: You design your own bookmark—with a small picture, a quote, a pattern, or whatever else you like. We’ll then laser-engrave your artwork. It’s a keepsake for you from the 2024 Long Night of Science—or a gift for your loved ones. After all, Christmas comes earlier every year ;-)
