Reading physical books is not yet a lost art and Kyouei Design's bookmark that also functions as a reading light could prove to be very popular.
When not illuminated, the bookmark is translucent except for the circuit that will provide a reading light for the reader when needed. The bookmark illuminates by having the two ends pushed together and the light is strong enough that it would make it easier to read in the dark without disturbing others.
This reading lamp bookmark is perfect for avid readers and people who enjoy having items that make their reading experience a little bit easier. Ideal for camping or for reading without disturbing a partner's sleep, these bookmarks are worth paying a little bit more for a quirky and multi-functional product.
This Bookmark Simultaneously Functions as a Reading Light
