USPS Foam Boxes and Insulated Containers

Marko Foam is very excited to offer three new molded insulated containers specifically engineered to be used with the Flat Rate/Priority Mail Postal Boxes. Marko Foam insulated containers are designed to meet the highest standards for durability and temperature control. All of our molded containers feature a locking lid for a snug, air tight fit. These containers come with a .75" wall thickness to maximize your usable container space, insulating value and durability.

Take the guesswork out of shipping with Priority Mail Flat Rate. These boxes can be used for both Domestic and International Priority Mail. Whatever fits in the box ships for one low rate. Along with a fantastic freight rate you will get the outer corrugated box for free from the online postal store. www.usps.com
