This Upcycling idea comes from Berlin. Every notebook is unique and contains about 50 sheets (100 pages) of blank, slightly yellow tinted, acid-free 100% recycled paper. The corners are rounded to avoid dog ears. The measures are 8.27 x 5.12 inches (21 x 13 cm), small enough to fit in a small bag. A rubber strap maintains this unique journal in an excellent condition.This notebook is reusable.
