    Sweetheart is always in.

    Lost my hair a few years ago to a brain tumor, including my eye brows and my eye lashes. They're all growing at different speeds but I have enough for these lashes and I am so thankful!

    GORGEOUS!!

    This is my second time ordering the sweethearts in Brunette and I absolutely love them. Black always seems too harsh for me so I love that there’s a brown option. They’re extremely comfortable, once I’ve had them on for a full day or two they soften and I can hardly feel them. Photos are not even filtered! Highly recommend!

    Don't love.

    Super thick pokey band. Bad fit for me. I like the sweetheart! I absolutely LOOOOOVE the weightless 3. I like the fullness of the flirt but they are sooo uncomfortable. I won't buy them again and I haven't used all from this box.
