The books offer a lovely visual adventure, that celebrates kids’ curiosity, rewards their attentiveness and delivers them new knowledge in a fun way. The many customization options make the reading experience more immersive. My daughter and her friends loved to find themselves in the stories. The books were delivered promptly. The unboxing experience is surprising as even the cardboard packing box has a special design, meant for children to enjoy. Communication was timely and smooth. Librio is a very well thought, well designed, excellently delivered experience for kids (but also for parents :)). Thank you!
