The Hang2it matt satin shower curtain comes with a sheer window and snaps away fabric liner to keep the water inside the bathtub. This shower curtain is very easy to install and does not need shower hooks to attach to the curtain rod. Just slip the grommets over the curtain rod and you are all set. The matt satin shower curtain is made with the highest quality 100% polyester fabric that provides a soft feel to the hand and is machine washable, so it can stand the test of time. This premium shower curtain uses our patented Hang2It technology that has been trusted by tens of thousands of customers worldwide. The replacement liner is also made with the highest quality 100% polyester fabric that can be removed and installed in seconds. The window will allow you to keep the water inside the tub and allow fresh air in, preventing the liner from flapping against your body, as traditional shower curtains do.
