links fixed :o sorry guys
ok i start a new cardboard JP, but that is not the news
if you see this pic
you can see the diference betewen the top of the pipe, and the lower part(or the larger)
hope im not incorrect, but all the JP cardboard or not are wrong, or is the same diameter, but put more lowered than the central pipe.
i start my new pack makin that part more big like on the pic
so please tellme if your JP are like the pics or the tube is one shape
