This bathroom glass shelf is made with extra-thick (6mm) tempered glass, safe to use and suitable for children. When it is broken, it will shatter into small particles, rather than be broken into jagged pieces like flat glass, which is unlikely to cause harm. It is made of strong, durable and rust-resistant aluminum to ensure durability and longevity. Suitable for humid environments such as kitchens and bathrooms. Notes: -Please allow a slight 1-3cm difference due to manual measurement. -Please allow a slight color difference.
