Sharpie Permanent Markers

What is this?

Black markers. Permanent. 

Why did I buy it?

There are times when you need a pen, and then there are times that you need something a little more durable and thick. Sharpie is a name you should be familiar with already, which is not to say there aren't better markers out there - Sharpie is just the one you will find everywhere.

They work. I like them.
