that's what she saidThe only drawback for me is if you clench and they get really wet they will slip around.
I can't tolerate the "softy bits" so I have to use tape...but you're right about the polyvinyl chloride, so what I've started doing is adding a layer of the below (allegedly) non-toxic adhesive tape over the top of the non-adhesive vinyl tape.This tape is made of Polyvinyl Chloride. Some say, don't put it in your mouth
Going through my pipe collection, I see that many vulcanite bits are in danger of breakage from my teethThis may be an old thread but I thought I would respond anyway. I probably have 50+ pipes and every one has a softy bit or a similar thing. I am a clencher and often have a pipe in my face and cant smoke with out them. To each his own!
