All depends on what youre trying to get into the county!
When I went state-side an took a record bag full of wax, I put my bag on the x-ray conveyor an walked through the metal detector...
....beep.... as usual!
But by the time i had emptied my pockets - A crowd of security had formed, and politely-asked me what was in the bag!
When I opened it up - they all had a little chuckle an ushered me on!
I guess 12’’ solid disc shapes, with a hole in the middle could be mistaken for a whole range of weaponary/drugs/illegal material.
