A packaged body includes: a prism-shaped packaging box 1 having a bottom; a pair of top and bottom shock absorbers 30 accommodated inside packaging box 1 for sandwiching a substrate storage container 10; elastic members 50 disposed between substrate storage container 10 and each shock absorber 30; and reinforcements 60 for reinforcing each of shock absorbers 30. In some embodiments, the vacuum bag may include a semi-permeable dirt bag having a top edge, a generally flat collar having a top edge, and a first opening in the collar configured to accept a dirty air nozzle, where the top edge of the vacuum bag does not extend beyond the top edge of the collar. The coaxial cable includes inner and outer conductors and a dielectric positioned therebetween. The spacers not adhering to the surface glass panes are spaced from corners of the surface glass panes.
