new pipe

my friend has a pipe that the bowl is actually on the inside of the pipe.

the way it works,

you pull off a seperate peice from the end (its a 2 peice but still very small) and put the herb inside of it, and the actual chamber has a screen (not sure if he added it tho) and its so nice because it wont fall out if he just packs it for later and puts it in his pocket.

im wondering if anyone knows of this pipe and where i could buy it online. thank you for your help.

I got the collet wooden pipe that sounds just like that.YOU cantwist offthe top and put your bud in and the flame goes through a whole in the top.Kinda like a wooden vaporizer!
