And what is it called?

In the comments on the pic it said copper wire I'm not sure where you can get it though

It's copper wire. You could probably get it at Lowe's or Home Depot.

Looks like copper wire..

Could probably find it at a hardware/home improvemnt shop..

copper wire, hardware store. You will likely need metal cutters for it. You can buy a thinner more pliable type in most craft stores in the jewelry making stuff.

its just heavy gauge copper wire---you can get it at Michael's i believe. Hardware store might be cheaper or have the thicker gauges (craft stores will sell super thin all the way to medium or higher, depending on the store).

Thanks!!
