and Crayola brand secret writing pens (WOW!!!!). There are about 8 pens in the set. You write secretly with two of them and develop the image with the other six.
I had something like that as a toy about 20 years ago. A single pen with tips on both sides. One to write, the other to develop. Didn't they have it in America also? Hadmut
