The smoke is at a high enough temperature coming out of the bowl hole to vapourize the clear coat on the plastic pen tubes, i dont care if you believe me, im not going to go link hunting but all i know is i dont use them in any of my bong smithing anymore. The smoke is cool enough after being filtered through water so that you can use a plastic chamber with minimal risk, but not the stem.
