I do not realy undersand why people are complaining about it bleading ITS A PERMANANT MARKER NOT A BALLPOINT PEN FOR CRYING OUT LOUD. IT IS FOR LABLING NOT NOTE TAKING. WHY DO PEOPLE HAVE TO BE SO STUPID

Bleeds through regular paper as expected. Works great for writing on plastic sticky tabs.

These are perfect for labels. I mix essential oils and use white artists tape for the label - Sharpie Ultra Fine is the perfect marker for that!

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.

Just what I need when I must hand write something on a label - the width is very very fine, perfect.
