Creating your XpresspaX system for your media needs is easy. Just select the container size and color you want, then add the XpresspaX inserts to match your media. All inserts are the same size and fit both single and double containers. It's a “one size fits nearly everything” system that's flexible and easy to use for all your off-site or in-house media transportation and storage. XpresspaX containers are built to protect your media and other goods. To prove it, we asked two independent laboratories to put our containers through a grueling series of standardized tests. The results:XpresspaX containers have been certified to withstand the rigors of transport--dropping, shaking, water and penetration.
