Jesse’s Girl Wateproof Liquid Eyeliner pens are on sale at Groupon. I love these and I just bought a set. I love Groupon Goods! I don’t have anywhere near me to buy these in store, so I snagged this deal. It’s a two pack for $8.99. With tax and shipping it comes out to $12.81. These typically sell for $6.99 each. They’re waterproof and I’ve used them in many of my videos.
