I wanted the flower screens, but they were sold out. The jacks leave a lot of space open between the prongs so stuff still gets through. I can’t even use them for the slide in my bong. My friend has the flower screens and they work great for her bowl and bong, because they don’t leave large gaps. Additionally, I’ve noticed as I go through the pack that a lot of the jacks on the bottom of the jar have the stem part broken off, so they’re not really usable. Please restock the flower screens!!
