INVISIBLE INK

 ‌        Once upon a time, I was walking on streets there were a sales brochure who were selling invisible ink. He was telling story and I found it was very interesting, and I lost my self in it and it was..Sales boucher : "When I was a kid, I love to use invisible ink – I used to take some lemon juice, apply to paper with a brush or stick, and then heat over the light bulb in one of our living room lamps. Voila! Brown lettering would appear on a blank white sheet of paper. A bit unsophisticated perhaps, but it worked. I didn’t really have any secrets but, it was the mere fact of writing invisibly that made it so cool.

‌But if I tell you that now you don't to apply any fruit juice, now it becomes too easy to use. Now, we are providing a light behind this pen and you can easily convey your secret messages.

‌You could use the invisible ink pen to create a secret message on your paper, and no one else could see what you'd written. Isn't it amazing?

‌Do you know the history behind it? Let me tell you, In ancient times people use this pen to convey secret plans and messages during wars. You can see, if you collect information regarding first world war. "

‌This is how the sales brochure convense me to buy this pen and I purchased.
