I wish there were better alternatives to the Sharpie because the smell bothers me. However, the Sharpie was invented in 1964, and nothing better has been made. It's a permanent marker. It bleeds through paper like nothing else. The ink smells bad (to some people). It writes on almost anything. It comes in every color. It comes in every size. It's the best laboratory marker because nothing smudges the ink. You've used it. I've used it. Astronauts use it; not even they can think of a better marker. Everyone has used it. It's a Sharpie.

It’s a sharpie :)

It's a sharpie. Nothing to add.

Everything as expected. ..

This is the only permanent marker you'll ever need. Perfect for everything.
