I got this hilighter thing that has a secret metal pipe in it. and it came with this little baggie of these small round things that have small holes in them kinda like a strainer. what are they. and what are they used for?
its like a filter, stick it in your bowl so you dont inhale ash, they are called screens btw i use em, some people dont tho because they can lower the amt of weed in bowl and they can fall out in glass bowls, but i make sure to get bowls that allows the screens to fit well.
so i just stick it in the bottom of my bowl? and how often do i have to replace or clean them? i got like 20
smoking like 3x a week, ive gone through three in the past 6 months. you can clean them, but when resin makes it so 50% of the bottom is black and is REALLY hard to get off, then switch. also force it down as far as you can in the bowl.
