Should I bag hard candy or not?
If you can shrink wrap them, do that.  They will likely get sticky if they are just bagged.  Manufactures bag them air-tight to keep the humidity out.  Per @sourd'oh pertinent note:


  "sugars you've inverted by cooking the syrup will become very hygroscopic and absorb humidity from the air"


Burying them in a bag of rice might protect them from humidity as well as preventing from looking as chalky as they would with confectioners sugar or corn starch. Speculating on the type of rice? I'd say Sushi rice would be least chalky.   

p.s.  Chef Hats off- they look awesome!
