The blue agave core has leaf bases which each look like a rhombus (squished square), not a hexagon.

Some of the upper leaves of the core could be left attached to the upper portion of the core. The lower 3/4 of the core would be grasp-able, so as to enable easy removal of the attached ground glass stopper ("cork").
