Yes & Know Invisible Ink books

[Etch-a-sketch]

Does anyone else remember these? I loved these and they had cool invisible 'decoder' ink pens that came inside the package. We used to use them a lot if we had to take a long trip in the car on holidays.

Yes & Know books were so cool, you could’ve sworn they were magic! Shame the ink used to dry up though. You could get a little more out of them if you soaked the pen in water for a bit...hehe. I liked the Mr Mystery ones.

I had one of these in the late 1980s, I gave it to my Sister after I had a clearout & can't remember what she did with it.

The pens used the same ink as the colour changing pens from those 2 colour flet tips that were popular in the mid 1980s.

I remember stocking Fillas well, once or twice my parents ordered some presents from them, but didn't like the postal charges.
