Kyouei Illuminated Bookmark
If everything you read is on an eBook reader, skip this one. Otherwise, the Kyouei Illuminated Bookmark can add a little extra functionality to the traditional paper or plastic bookmark and looks cool to boot. Its silver ink circuit is printed on a special film, transmitting light when it’s folded over a CR2032 lithium coin battery, the latter squeezed between its two contacts. Its two LEDs aim one way so you can point it towards your page, making this a compact directional reading light you’ll always have with you for when you’re out of other options.
