It's not easy looking for, travel size watercolour pans. They vary and that can be confusing. I discovered one called a sketches set by Winsor and Newton. Another good brand is artistro. They also do a travel set with 48 colours. These include metalic and neon as well as the traditional shades. It also comes with a water brush pen pencil rubber ,sharpener ,paper and sponge. I find these very handy due to only having a small space to paint.
