Since we have three different notebook collections, each is dedicated to a specific purpose. For example, the Dingbats* Pro collection is mainly used for Mixed Media (MM) techniques due to the thickness of the paper (160gsm) and its durability. Whereas the Wildlife and Earth Collections have 100gsm Fountain Pen (FP) Proof paper, where the former is used for general purposes while the latter provides guides and extra features to kick off your journaling journey.
