What is an eye gloss pen and how do you use it?

I got a vanilla shimmer Color Twist eye gloss pen by Avon at a sale of a rep going out of business, thinking it was lip gloss. It comes in a plastic ';pen'; which you twist the bottom of to release cream colored liquid through a felt tip. How do I use it?

you kind of glide it over your eyelids where you would normally put eyeshadow or eyeliner.
