Travel watercolor sets

I've been looking for portable watercolor sets to take with me when I travel. On a recent trip to Czechia, I bought Koh-I-Noor watercolor wheels with some basic colors in favour of pre-made palettes. The set I chose contains just two wheels and a total of twelve colors. I wanted it to be as lightweight as possible. The good news is that you can expand the set and add more wheels if necessary, and they all fit together nicely. The set is very light and about 3.0 inches in diameter.

Additionally, I got an empty tin box so that I could fill it with the colors I wanted rather than pre-selected ones. I picked up six colors from Renesans, a Polish brand I have not yet tested. Each paint was $1.15 and I spent less than $15, including the tin box. I’m excited about the possibility of expanding the set's paint selection and including miniature brushes.
