The Green Monkey Javan 4-piece grinder is great for herb enthusiasts. Whether you're at home relaxing or out with friends, it's a handy tool. It's perfect for people with weak grip strength as the strong magnets hold the layers together and make it easy to access each part. It comes in multiple sizes to suit your needs. The outside has deep grooves to help you grip and turn it easily. The bottom chamber catches extra kief, and you can use the scraper tool to handle it.
