Due to the fact Holbein very recently released their brand new 50 set of Holbein Artist Watercolor Pencils, I thought it would be a good idea to compare them with the Caran d’Ache Museum Aquarelle. For the longest time, the Caran d’Ache Museum Aquarelle Watercolor Pencils have been widely considered the best water-soluble pencils on the market.
