Ravensburger Aqua Doodle additional pen

Original accessories for the Aqua Doodle® painting system. As a replacement or so that several children can paint at the same time. Aqua Doodle® is a fabric mat with a special surface that turns blue when it comes into contact with water. Even the little ones can paint to their heart's content! The special pen looks like a felt pen, but is only filled with tap water. It is therefore completely harmless and can be refilled indefinitely. With the additional pen, several children can paint at the same time.
