The glass shelf bracket is constructed of HEAVY-DUTY Type 304 premium grade rustproof stainless steel, with added 18/8 Chromium/Nickel content to protect against corrosion & rust, suitable for humid environments such as bathroom and kitchen. Smooth, round corners protect you from accidentally scratching and keep your bath safe. When broken, it will crumble into small granular chunks instead of splintering into jagged shards as plate glass, unlikely to cause injury, safe to use & kids-friendly. T
