8mm extra thick tempered glass: Safe use and kid-friendly. When the tempered glass is broken, it will crumble into small granular chunks instead of splintering into jagged shards as plate glass does, which reduces the risk of injury. It is ideal for holding your daily-use toothpaste, make-up, lotion, or even other big toiletries. Chrome-finished rail avoids items from toppling off. Besides, the glass bathroom shelf equipped with a towel rail allows you to hang your towel whenever you want.
