its a good idea but its better to find a metal tip that has a really small hole as opposed to your unique screen idea, the metal in twist ties is very malleable(bendy) and most malleable metals have a low burning point, and even if its not burning my bet is its giving off nasty toxins.

An even better thing to do would be to go and pick up a glass one hitter from a shop cause then all your smoking is weed and it tastes 50 times better, plus its been proven that even though the lighter flame is not directly on the plastic the smoke is still hot enough to activate narsty chems in the plastic which we all no is a bad thing

but a pen pipe was my first smoking device i ever made and i know that they do get the job done pretty well

The other night I had just gotten finished rolling my ounce of weed into joints. (I realize it degrades quality, but I like to have them readily smokable. It gives me a taste of how it'll be once it's legal.) When I finished rolling the last joint, I had just enough weed left on the tray to load my one-hitter. I decided to do so. I didn't feel like going up in my attic, so I just made an identical one out of an identical pen that I had in my pocket from school. Rating: 5
