These are 316L (surgical) stainless steel. A pack of these will last you forever.
You cut a piece from the stainless steel and compress it with your fingers into a plug that fits tightly into your E-nano gong. You want the plug as tight as possible without reducing airflow.
Once you put push your SS wool plug into the GonG, just tap it hard on a desk, on both sides, and blow through it, until you see no more SS wool fibers that were shed during cutting/handling coming out.
You want to push it in to the point where you leave a few millimeters from the heater to the SS wool substrate, enough room for your concentrates.
Once it's in place you don't have to mess with it again for quite some time (I have a dedicated Gong for this purpose). Until you feel airflow, and performance, is being reduced by build up. I have put through MANY dabs on the same piece of SS wool before removing it. Then you can drop in ISO and reclaim.
You just drop your dab on the top of the SS wool through the top of the Gong.
It's just personal preference between this and cotton.
I like SS wool because it's impossible to off-gas (cotton can and does singe at high temps) so I can high temp dab with dial at 10 without worries.
Also like that I can just drop dabs on it without messing with it each time.
Also like that I can reclaim from it if desired.
Here is video I did of a high temp convection dab on SS wool:
Thanks for the call up
@herbivore21, hope you're well mate.
