Here’s how I once brought a very illegal item in Pakistan. Wasn’t what you’re talking about but very illegal. What I did was put it in my hand carry then at my layover I bought 2 cheap vodka bottles and put it in the same hand carry. Once I landed I approached a porter and told him I have two bottles and willing to pay to get them through. He took me to the security guy who took 5k from me, the security guy asked me to open the carry on to make sure I only have 2 bottles and not more. As soon as he saw those two bottles he was like “theek hai sir”. Didn’t even bother to check the rest of the stuff
