Tape the cardboard ends securely by wrapping the tape gun around the circumference of the package several times.
The package should be so tightly wrapped that the object can't slip out. If it isn't, fasten cardboard around the top and bottom, then tape it well. For extra protection, wrap the entire package in another layer of bubble-wrap and securely tape both ends.
You're object is now fully protected against bumps and shifting. Place it in a box marked fragile, along with your other glassware and delicates.
