Our laboratory or chemistry tubes are packaged in a foam rectangle with cutout inserts that hold the tubes. I save these inserts
and use them to hold insulin tubes that we send home with clients. The inserts help protect the tubes from breaking on the
trip home and keep the tubes cold during transport. The inserts also keep the tubes from rolling off the refrigerator shelf.
