 About Kosco

Since 1968, we at Kosco Flags have been supplying our customers with what we believe to be the best flags, flagpoles & windsocks made. We take pride in keeping the majority of our products made in the United States . Even though more and more goods are being imported from overseas, you won’t find a foreign made American flag to fly at Kosco Flags.


Kosco Flags was started by two patriotic veterans, Seymour Cohn and my Grandfather, Clayton Koskinen. We have been located at the same location on the corner of Glen Flora & North Avenue in Waukegan since the late seventies. I have been with Kosco Flags since 1982 and Gary Robison joined us in 1991.

While checking our website, you will find we have a large variety of colorful and unique decorative flags, banners & windsocks to brighten up your home or business.

If you are looking for a custom flag or banner for your business, school or origination, please send us your design for a quote.

Gary or I can be reached by phone or e-mail for help with your flag & flagpole needs. We look forward to working with you.
