So simple, yet so brilliant. These book page holders are designed to fit around your thumb, like a ring, making it possible to read a book with one hand. The shape of the thing is based on the contours of the fore and aft pages; placing it on the spine prevents the pages from closing back. And not only that, they’re thin enough to be used as bookmarks. Simply clever. Comes in different colors and sizes.
