Thank you for viewing. I am selling this because I bought it for studying, but I no longer have the opportunity to use it. This is a rare item, and it is currently unavailable at the list price. Below is an excerpt from Google AI describing each book: "How to Improve Natural Depictions in Watercolor: Beautiful Techniques of Professionals" Author: Keiko Kobayashi Publisher: Ikeda Publishing Content: Explains how to express over 100 colors with the recommended three colors, and watercolor techniques such as sprinkling salt and using masking fluid. *As shown in the last photo, there is a slight stain on the top of the cover. This product has no sun damage, but it has been stored at home, so please refrain from purchasing if you are sensitive to this. Please feel free to contact me if you have any questions.
