I have only traded panties with girls within my own country, so I don't have direct experience with overseas clothing parcels, but I can tell you that if the package isn't opened by postal inspectors, customs, or Homeland Security, it WILL be opened by the Agriculture Dept. at the border. They are very careful about not allowing propagating organic material into the country without proper certification from the sender (they stopped some flower seeds I ordered from Thailand just a couple weeks ago!)
So... just how dirty ARE your panties?? hahaha
I'm (obviously) a guy...
Everyone: "OBVIOUSLY?????????"
Me: "Hush!"
Tips for those sending panties in the post:
DO NOT send clean ones. (In fact, send two/three day ones...) The recipient doesn't give a FUCK what they LOOK like... A DIFFERENT experience is desired...
Wrap the USED kninnies in Saranwrap, Cling-Film... Fold em and wrap em TIGHT... THEN, put them in a Zip-Loc bag and seal... (The idea being you don't want to LOSE any of the... Let's say ESSENCE...
Stick the bag in a padded envelope and Mail 'Em!
It's that easy.
