The shower phone holder is made of high quality ABS, EVA and other friendly materials. Featuring a double-layer waterproof construction with an internal waterproof strap design and full wrap-around storage, it is impervious to water vapour and shower splashes. Note that it is forbidden to completely immerse the product in water. The unique design of the retractable adjustable holder not only has 360 degree arbitrary rotation, it can easily achieve free retraction, which makes the up and down adjustable angle increase significantly. The shower phone holder can be extended by up to 2.3in, allowing the phone screen to be displayed at the right angle.
