Grinders can be used to crush up your Cannabis Flowers and Buds with ease in no time! These grinders have very sharp grinding teeth that are positioned just right to grind any type of herb you have, from lighter to more dense buds leaving you with an even fluffy consistency for a great high, and allows you to shred your dry herbs or tobacco while simultaneously dispensing your herbs. Once your herbs are ground to your desire, simply push the button on the bottom of the grinder to raise the surface above the diamond style teeth, and push your herbs out. The bottom half of the diamond teeth is made of anodized aluminum, while the top half features glass, and both halves are held together by magnets. Let the 2-Piece Pop-Up Diamond Teeth Grinder make a quick grind and roll easier than ever before!
