[3] In 1910, in a $200,000 deal between George Vits and the eastern capitalists, all offices and manufacturing were moved to Manitowoc.

During World War II Mirro retooled its factories to make aluminum products for the military.

When the war ended in 1945, the company expanded into aluminum toys, making the popular Sno-Coaster saucer shaped sled.

[13] In late 1971, Mirro purchased Cruisers, Inc., of Oconto, Wisconsin, a manufacturer of Fiberglass boats ranging in length from 16 ft to 25 ft.[14] At its peak, Mirro was the world's largest manufacturer of aluminum cooking utensils, and over time it had as many as eight plants in three states, with products ranging from pots and pans to small boats and aluminum siding.

Mirro also closed its administrative offices in Manitowoc at that time, ending the company's 118-year history in the area.

[citation needed] The manufacturing facility in the industrial park on Mirro Drive on the northeast of Manitowoc, was purchased by Koenig & Vits, Inc., when it closed.

Plans for redevelopment of the remaining portion of the building occupying the south third of the block into the Mirro Shops, are currently on hold.

ft. distribution center next to the plant on Mirro Drive was sold to Orion Energy Systems by Koenig & Vits in 2004.
