There may be other purposes, but with our grinder you can mainly:
Crush and grind the buds without making the effort with your hands and in a much more efficient, clean and effective way.
Save yourself the "disgust" of your hands ending up full of resin when it comes to crushing and / or crushing flowers.
Get more out of CBD flowers and marijuana, as you won't waste your resin.
Make the material perfectly crushed and crushed and then enjoy it much better. With the hands, the result is not even similar.
