    5 stars

    These folks redefine luxury and customer service. I used to buy/sell to Fashionphile, The RealReal, and Instagrammers all the time, and now I'm a convert to Mark and his team. They've invested hard in a great program while retaining that small business touch and speed.

    Mark was highly effective. He assisted me in an honest way, sending me a quote after evaluating my handbag photos. Once I accepted the price, he emailed a shipping label to me quickly and got the job done with high efficiency. Thank you!
