I also am an avid fan of Essence products. Their products are priced right and are excellant quality.
I must say that I am not a daily user of liquid eyeliner but when I need to glam up, i find it just the right product to do so.

I would not use the thick pen but it could serve useful in the future. I love the thin tip as it offers precision and not hard to draw a straight line.

and yes, this product is durable, it lasts...and lasts...and lasts...

for those who love liquid eyeliner, give this a try, you have nothing to lose...
