I did some fire prevention training at home today - all part of lockdown employment - and there were some invisible sections that needed illuminating.
It so reminded me of something from childhood and all I could think of was invisible writing but I'm just foggy about what it actually was.
For some reason I have those Witch pens in my head. Were they for invisible writing? Were there other invisible writing pens?
Can anyone de-fog this?
I think there were a whole load of different "invisible ink" pens/sets available; I had one that you wrote the message with the invisible ink pen, and revealed the writing by using the accompanying felt tip/ marker sort of pen. Thats all I can remeber about it, would have been 1968 to 70 ish.....
ReplyDeleteThey were a craze spinning off from the spy and secret agent boom I agree Spymeister! The rest of this comment is invisible!
DeleteI remember the Platignum Man From Uncle pen set with its cartridges of pink invisible ink (heat activated as i recall) in Mrs. Sell's corner store next to my school, but it was WAY too expensive for me!
ReplyDeleteMrs. Sell! What a great name for a shopkeeper Looey! Wonder who got the set in the end!
