Our stainless steel ball agitator comes free with a 4 piece grinder purchase. However, you may want to grab a few extra to keep handy or give to your friends!
Instead of using a grinder coin that gets dirty (and can be harmful to your health), you can place this agitator ball on top of the sifting screen of your 4 piece grinder. After shredding your herb, shake the grinder gently so that the ball can help break down more of the herb particles and press them through the screen for a finer kief output.
By the way, WE ARE THE ONLY MANUFACTURER to supply a stainless ball to agitate the pollen through the screen in the catch basin. Just another reason The Ripper gives you the best grinding experience!
