This bird cage provides a large, cosy place for your birds to fly and play safely. Durable and sturdy frame: The large bird cage is made of galvanised steel. Steel is an exceptionally hard and strong material. It offers sturdiness and stability. Galvanisation provides better protection against corrosion and is useful for products that'll be used outdoors as well as in harsh environments. Mesh design: The mesh design of the outdoor bird cage helps prevent mischief and unexpected accidents while enabling ventilation. - Berkfield Home Bird Cage with Door Silver Galvanised Steel
