Masterliner is a crayon eyeliner that is mess-free and handy to have in your handbag for a touch-up when out on the go. It doesn't have the 'poke' quality like other eyeliners and lasts for a good chunk of the working day. For the brand and quality, I think it is reasonably priced and lasts for a good month or two.
Masterliner is available for purchase at Coles for $13.50 ($9 on special).
Summary Easy to apply, long-lasting, and accentuates the eyes beautifully.
