This is the upgraded Cali Crusher 2.0 Grinder. The original patented 4-Way Quicklock feature eliminates cross threading incidents and jammed grinders. This lock system has been improved by making the grooves finer and more pronounced. The screen is removable with the use of a "Phillips Head" screwdriver.

 The new Cali Crusher 2.0 Grinders have a deep engraved logo. Each grinder is crafted from top-shelf Aerospace medical grade aluminum with indestructible radial cut blades that are covered under a Lifetime Manufacturer Warranty! Notice that the bottom catch chamber is not only 2x larger than your average grinder's catch, but it also has our original smooth rounded contour design for easy access and finger scooping your pollen. We've taken every problematic feature of the classic grinder and redesigned it for overall improvement.
