I use the garnier roller pen thingy and i have been using touche eclait (sp) also, not sure if it is a combination of both that makes the difference, but when i use them my eyes definately look a lot better!

I have had the pen for over a year i think and i still have not finished it, granted i dont always use it every day, but due to the fact that you dont really use much of it, it lasts forever!
