Even if you live in an era of electronic computers, cell phones, and the internet, pen, and paper are still irreplaceable. Even as you surf the internet, you probably have a pen that you can easily use to take notes, write down phone numbers, or even draw pictures!
Rose gold ball pens are so cheap we don't even think about it anymore – you can have a mug on your table containing a dozen or more different pens that have strayed from nowhere!

A ballpoint is a pen that uses a small rotary ball made of steel, brass, or tungsten carbide to distribute the ink as you type. All pre-ball pens use aqueous black ink which flows through the pen in a capillary motion.
That pen is what the world has been waiting for! The epicenter of the pen is, of course, a ball.
These balls act as a buffer between the material you're writing on and the quick-drying ink on the pen. The ball rotates freely and curls the ink as it continues to be fed from the ink tank.
The ball is held in place with the gap between the ink tank and paper. and even though it's cramped, there's still plenty of room to rotate as you type. As the pen moves over the paper, the ball rotates and gravity pushes the ink into the tank and onto the ball, where it is transported to the paper.
