True thickness is consistent but, for testing a Speck ultra thin, this delicacy is often at the expense of real protection during a fall or shock received in the carrying bag. The no worries, protection against minor scratches of everyday life and protection when traveling.
Only flat, packaging already commented here, very light indeed, a plain envelope without quite amazing bubble.
No worries for me, I received my shell nine days after ordering. For this price there is not really enough hesitation.
