Thats funny shit.
I put it in my carry on inside of my soap, in one of those plastic soap containers. Cut out a cubby from the bottom of the soap for space and tape the piece over your stash.
Get a clear soap holder and a dark colored one, put the clear one on top and the dark on the bottom. the clear makes it easy for them to see and not suspicious, the dark bottom just kinda hides the cut and the tape a little. Use a brand new bar of soap to start but rub the top off a little so it looks well used. It also helps release some smell for deodorant. Be sure to put your real one in the suitcase or else,
what do you need two soaps in your carry on for, sir?
I've only done this with cheap weed, nothing too damn stinky tho, so not sure if it's super dank.
