Reddit reviews Knitter's Pride T-Pins (50 Pack)

Personally I ALWAYS use a metal screen. Here's a link to the ones I bought 3 years ago: Amazon
But...I take some of these bad boys right here and push it through the center, then drop them into the hole of the pipe. (Some bending may be required) This will ensure you never lose the screen when you blow out the ash. I personally believe that every hit is 10X as smooth with a metal filter, and eliminates the worry of sucking too hard and pulling ash into my mouth/bong.


Now, 10 other people below me are probably going to say "Screens are worthless, you don't 'need' a screen" and they're perfectly right.
But I enjoy to smoke my way, and them, their way.
My recommendation is to try it both ways and you decide.
