Rust-proof: The bracket is made of 304-type high-quality stainless steel with 18/8 chrome/nickel content added to prevent corrosion and rust, suitable for wet environments such as bathrooms and kitchens. Tempered Glass: 7mm extra-thick tempered glass, safe to use and suitable for children. When broken, it will break into small particles instead of jagged pieces like flat glass, less likely to cause injury. Space-saving: After using KES's beautiful and stylish corner glass shelf, all bathroom toiletries such as shampoo, conditioner, liquid soap and face cleanser will be organized and easy to access. It is a good choice for small and limited bathroom space. 2 Installation Methods: There are two installation methods for this shower corner shelf. The rail can be installed on the bathroom corner shelf to prevent your toiletries from sliding off easily. In addition, the rail can be installed under the shelf for hanging towels. Package includes: 2 pieces of 7mm thick tempered glass (with rails), 4 rust-proof stainless steel brackets, 1 hardware bag, 1 installation instruction. No need to buy additional hardware.
