This is a pack of 6 fine screens for your Volcano Easy Valve chamber.
The chamber uses 2 screens, one on the bottom and one on the top and they need to be replaced periodically.
These high quality stainless steel screens can be cleaned with isopropyl alcohol a few times however when they get significant plant material built up, they get clogged and need to be replaced.
The Easy Valve system comes with normal screens and these fine screens enable you to use very finely grind herbs in your easy valve chamber without particles escaping into the collection balloon.
Just like all Storz & Bickel products, these screens are made in Germany to high manufacturing standards, using food grade stainless steel.
