Air pens magic are literally magical. They come from the Centropen workshop. In the set, you’ll find 4 basic colours and two changing pens thanks to which you can change colours – sometimes they’re also called “erasers”. However, they don’t cause the colours to disappear, just to change their original colour. On the pack, you’ll find information about how colours change after applying the erasers. One eraser pen is a classic one that we know from school and the other one is an air pen.
