    Cheap plastic, Stains
    Color: White, Color: White
    Cheap plastic holds the soap. The pump is also cheap plastic. The fake marble stains easily. Water builds up in the bottom and causes a stench so you have to wash it everyday. Not worth it, keep looking.

    Great product except….
    Color: White
    Love the base of the holder and color! Plus the brush was a nice add-on. The soap dispenser was not as solidly made as rest of product. Had it for 3 weeks hoping dispenser will last. Would give all high praise if they beefed up the dispenser.
