Ive received a couple of packages from across the pond in the last two weeks. What i did notice is that they punched a tiny hole at the top. I assume that this is to help with their digital sniffers. I saw a thing on tv about how customs are using digital sniffers instead of dogs. they said that they are much more reliable and dont have to take them poop.. Seriously though. if its packaged well and is vacuum sealed I would manage it would be ok (as long as its not a smelly substance like pot).. I dont order very much overseas, but this is the first time i have ever noticed a tiny hole at the very top...
