The 4" ball from Rome is made from quality stainless steel and is completely round. Unlike glass balls, they do not have a stem/throat or the ease of breakage. Designed as a garden accent they make a great reflective pop placed in a planter or garden bed. We have sold our globes to countless artists who have used them as components in their imaginative designs as well as to and interior designers for retail stores & hotels.
