To use the Javan grinder, pull the magnetic lid from the device. Load a nug in between the razor sharp teeth, replace the lid and twist. As the weed is ground up, it drops through to the next layer and is caught by a mesh screen. Pull the tooth layer out to reveal the contents. Since each layer is held together by a strong magnet, accessing each layer is simple. This makes the Javan a great option for those with weak grip strength, and makes rolling up an accessible process for all.
