Brilliant things are usually as simple as possible. Just like this clever bookmark designed by Kouichi Okamoto from Kyouei Design.
Called “Bookmark Light,” this little thing is a tech-looking bookmark that can be used as a mini light.
The bookmark is printed on a special film using the ink which transmits electricity. When you fold the film down and place the lithium coin battery (CR2032) between the marked ends, the bookmark will light up.
Bookmark Light is available in Japan, for JPY1,728 (approximately $17), and you can order it directly from Kyouei Design website.
