sew them into the cuffs of a pair of pants with some other physically similar material. put nothing but clothes in teh bag. nothing. check it.
the best way is to put it in back of ur logo of ur pants where it says the name brand of ur jeans and wear a belt trust me u will be good
my friend has smuggled ounces of weed back from africa to england several times in his shoe. once he had a joint in his back pocket and didn't know, walked past a sniffer dog nothing happened. don't be a pussy. if u wanna be really safe put the pills into liquid and into a small shampoo bottle, simple.
I worked with this dude from the straight hood, him and his girl got pulled over with a ounce of weeds and the fuckin hood rat shoved it up her puss! before he could even understand what was happening. Thats hood bitches for yah. i was like !
Theres a bunch of ways you could do it, but personally since you wanted to tape it to a shirt, put them in the seams or cuffs of something.
In the cuffs of yer pants at the bottom, slit with a blade and start stuffing, logo like mentioned is good and if you are bringing ass loads then crush and mix with vit-c pills. I have used all of these on international and domestic and never had issues. Just found a pic for an example.
