    High quality and long-lasting

    I've had this underwear for over two years and it's still going strong! The elastic has held up so well and the "silky" part of it is surprisingly durable; I've had no rips or tears. I find this style very comfortable and love the low-cut fit.

    THE MOST COMFORTABLE THONGS EVER!

    Comfy? Check. Seamless? Check. Sexy? Double check!

    I have maybe 15 pairs of these by now and I can't get enough. I've tried other thongs from negative and the silky thong is by far the most comfortable. More colors please!
