Pollen presses are a simple to use and humble tool that is already widely used to make hash coins, though it can also be used by recreational users for personal benefit. Even if you aren’t manufacturing hash, the use of a pollen press is a fantastic way to maximize your stash. Once you have the pressed product, you can then use it in so many ways instead of wasting it: vaporize it, dab it, and sprinkle them into your bongs or blunts.
