St Cuthberts Mill Botanical Ultra Smooth is a high-quality 300gsm mould made paper. It is made from 50% cotton and is acid-free and calcium carbonate buffered.
The absence of acid guarantees excellent permanence and resistance to ageing. The color is a very close match to Fabriano 5, and it does contain optical brighteners to give a bright white color. It is ideal for botanical watercolor painting as well as charcoal, pastels and graphite.
