Fingerbook is a small piece of wood that is put on your thumb to help keep the pages of your favorite book widely spread using only one hand, even when laying on your back. This Fingerbook-prototype is made of swedish pine wood, with a chip carved patternt. When not used the Fingerbook can be places on the bookmark and rests beautifully on your nightstand amonst other books. I imagine this product being sold as an upsell product in pocket shops, contributing to the valueing of this product being made out of a sustainable material.
