Coloring postcards that are not coloring pages (moe version)

A nice design is printed on paper with transparent ink that repels water. When you apply water-based fountain pen ink, pictures and letters will appear white.

It's really just coloring, so it's okay for people who are clumsy with their hands and those who have trouble thinking about color schemes.

You can consume ink that cannot be used up in a luxurious way.
