Do not do it! I had customs open a package of my pee panties and they actually wrote to the guy to come and pick it up. When he turned up to collect it, they really gave him a hard time about who it was from, and where and why etc., but they did end up giving him the package. When he got home the package had been tampered with and pulled apart and the whole thing was SWIMMING in piss – I never ever send out my items like that and so it seems the custom fellas had the last laugh.
I would never ever risk sending anything other than my worn panties outside Europe .. customs might not be able to track you down but they can certainly find your buyer. It isnt worth it and I would never ever risk that again no matter how much money I was offered.
