Grinder Features

Patent Pending Magnetic Closing System

The ZAM 4-piece FullMag is a cannabis grinder without threads, and without any center posts. All sections of the grinder are connected using powerful Neodymium magnetic rings situated on the perimeter, with steel rings placed directly opposite.

Got a Big Ol’ Bud? Throw It Directly in the Center!

No magnet in the center of the grinding chamber frees you from the burden of squished bud patties. Before, the center of the grinder was a “no-go zone”, but now it’s the optimum location to easily apply the greatest amount of torque.

Thoughtlessly Combine Sections. No Unintentional Rotation

The ZAM FullMag doesn’t require any special orientation to combine. You don’t have to line up any complicated shapes or solve any puzzles. When two sections of the grinder attract, a rubber O-ring is compressed, preventing any unintentional rotation. Patent pending

Meanwhile the grinder remains securely closed. Drop it on the ground, toss it in a bag, or even throw it across the room — it won't come apart. 

Customized Magnetic Pulling Strength 

Different sized O-rings can be used to control the distance of the magnets, and therefore the strength it takes to open and close the grinder.

Planning to take your grinder out on a trip? Use a smaller O-ring so the pulling force is stronger.

Are you planning to hang out around the house? Or do you have reduced hand strength? Use a larger O-ring so the magnetic pulling strength is weaker and the grinder is easier to open.

O-Rings Prevent Odor From Escaping While Preventing THC Deterioration

A smooth turning lid was prioritized, so while the entire grinder isn’t completely air-tight, the compressed O-rings do prevent smell from escaping. The O-rings also help prevent your herbs from deteriorating. 

Redesigned Grinding Chamber

The main grinding chamber has been redesigned to reduce the surface area of the inside wall. The wall height was reduced to prevent build-up and now acts as a guiding edge where extremely sharp trapezoidal teeth positioned close-by will propel unground material back into the path of the teeth.

Graspable Area - Diamond Knurling

Too many grinders have tiny lids that are hard to grasp! Increased part size in addition to deep diamond knurling surface texture guarantees that your hands are comfortable and won’t slip.

Collect Large Amounts of Golden Kief

Collect massive amounts of golden kief with a 60 micron screen. Fine enough to produce pure golden kief, yet large enough not to clog. Easy to clean, easy to replace.
