It is the shortest pen in the world, built on the technology of Leonardo da Vinci. It has no ink and never stops writing.
It’s called the Forever Pen. It is being advertised on a crowdfunding website and production will begin soon. It is so small that it can be easily attached to a key chain and even fitted with a zipper.
The principle is very simple, that if silver is cast in a thin tip, its writing leaves a light mark. Now it has been deepened by mixing some compounds in silver. This way it can easily write on the wall, paper, plastic and other places.
There are three types of metals on the back of which you can choose. That is, if you want, you can take a pen made of copper or you can choose brass or you can choose one of the titanium. That way we can call it a solid ink pan.
Its nib is made of a mixture of composite metals in silver which leaves a texture or a reflection when rubbed anywhere.
The introductory price of the Forever pen is 25 pounds or just over 5,000 rupees.
