Giving Back

Giving Back

As COVID19 continues to hold the country hostage, we wanted to show our appreciation for those who are on the frontlines putting themselves at risk to keep people safe and healthy during these difficult times.

Key Container coordinated with New American Foods and Cross Country Cookie and donated over 100 boxed packages of candy and cookies to local hospitals, fire and police departments as a Thank You for their dedication and sacrifice.

We have been fortunate as an essential business to remain in operation as a vital part of the supply chain but we also recognize there are those who aren’t so fortunate. Custom & Miller Box has also donated 1000 boxes to The Backpack Crew, which in partnership with E.P. Kids, is committed to continue providing food for families in need due to the untimely closing of schools.

We again, thank and appreciate you for putting your lives on the line for the sake of others. You are the true heroes. We’re all in this together!
