Flat Glass Solution screen

Flat Glass Solution makes inkBOOK Obsidian very sleek and the frames are on the same level as screen. It’s also lighter than a book and fits into your pocket.

Read comfortable, even at night

Uses light-emitting diodes illuminating the screen from the top, and not directly towards the user, causing it friendly for your eyes. It can be freely adjusted or turned off completely.

Support for many formats

The device allows you to open many popular file formats. inkBOOK supports the international standard of e-books EPUB with DRM (Adobe ADEPT).

As versatile as tablet

Install favorite apps

As one of the few e-readers in the world, inkBOOK allows you to install Android apps, which can significantly extend functionality of your device.

Opens PDF files, even the complex ones

Multi-column PDF files can be displayed in a single column of enlarged text. The reflow functions intelligently “cuts” the text of each column and creates one, with continuous text. This allows reading of the content more comfortably. This feature is not present in the reader Amazon Kindle.

Gigabyte for your files

8 GB of built in memory and option to increase it by up to 32 GB microSD card allows you to keep dozens of thousands of publications.

Check translations and definitions in the dictionary

If you come across a word you do not know – use the built in dictionary. inkBOOK lets you quickly search for definitions or translate words without leaving a book or manual.


After a few days with inkBOOK Obsidian I can recommend it with a clear conscience to e-books lovers which are paying attention to design, reliability and flexibility. At least it’s possible to install apps on the device.

Obsidian meets all my demands, which is very important to me. Display is white as a sheet of paper, interface is smooth, without ghosting while reading. You can create bookmarks and notes, and it’s usability rocks when you spend your evenings with e-books… Obsidian is all you need!
