During an exclusive interview with TMCnet, Rayner said the company spent 18 months and more than $1M to, “meet environmental challenges while maintaining a simple, sleek design.”

“It was an extraordinarily difficult project that many of the industrial design firms initially contacted said could not be done. The company went back to the drawing board five times to get it right, but it achieved its protection and design goals,” Rayner said.
