Maybelline Eyestudio Master Precise All Day Liquid Eyeliner

"My best friend's wedding in Costa Rica was fast approaching, and I knew I'd need makeup that would stay put in the heat all day long. After lots of research, I ordered Maybelline Eyestudio Master Precise All Day Liquid Eyeliner ($5, originally $7), and I'm so glad I did. I used it both for the bride's wedding makeup and my own face. Through 98-degree heat, there wasn't a single smudge. Even more impressive? We jumped in the pool and it still stayed put. This formula is pretty amazing.

Besides being a budge-proof eyeliner, the design is also easy to use. You can effortlessly achieve a straight line with the pen-like applicator. I gave both myself and my BFF a cat eye in just minutes - no Q-tip corrections needed. If you don't take my word for it, just read the 4,000 customer reviews on Amazon. Customers love the inky black color that never moves.

If you're in the market for a new eyeliner pen, this affordable option is the way to go. I have been using it ever since my trip and love it as much as the first day I got it." - Macy Cate Williams, editor, Shop and Must Have
