I put kleenex in the deli cup with a note on top reading "hatchling goes in here". I then taped the lid of the deli cup, placed it in a snake bag and tied the bag closed with the neck doubled over, just like I ship. I then packed the bag centralized with crumpled newspaper all around. On the lid of the styrofoam box, I taped the heat pack (still in the package) with a note reading "if this were a live shipment, heat pack would be activated". I put in a fake invoice showing proper documentation (number and type of snakes, to and from addresses), and closed up the box. I labeled the outside with
"Live Harmless Reptiles
1.0 Juvenile Pantherophis guttatus"
and
"Perishable
Please Avoid Temperature Extremes"
on alternating sides, just like I ship.
I then put the box in an overbox marked "Overbox" (since they require that) and mailed it in.
I got the report back (with pics of my box, pertinent details, and a 2 page report telling me it passed and detailing the type of packing job I did) within 3 days of sending it in along with my box and all of its contents.
