This is a watercolor paint set. I've gathered unused items and put them in a case, so they are unused, but many have hardened due to the passage of time. They are watercolors, so they can be dissolved with water, but it might be difficult for children to use. Also, a family name is written on them. We are waiting for purchases from those who understand the above condition. - Brand: GUITAR PAINT - Tube size: 12ml - Package: Clear case Thank you for looking.
