Descriptions
The GRAV® 3-Piece Grinder is made of CNC-machined aluminum, trusted for its strength and durability in the automotive and aerospace industries. If it’s good enough for astronauts, it’s good enough for us.
Add your dry herb to the upper chamber, packed with 19 aluminum teeth. Give it a few smooth twists to chomp nugs into bowl-ready bits. When your flower is sufficiently pulverized, it will fall through the cannabis grinder's well-spaced holes into the chamber below.
When you're done, separate the chambers and scoop out your ground herb to pack your favorite bowl. Use the included GRAV®-branded scraper to help—its edge is curved to perfectly fit the interior corner of the grinder. Get that green out of every nook and cranny.
The GRAV® 3-Piece Grinder is available in six easy-on-the-eyes colors. Comes with a small GRAV® carrying bag.
- High-quality weed grinder to give you the perfect size and texture for pipes and bowls
- Made of durable CNC-machined aluminum
- Includes aluminum scraper to get ground flower out of bottom chamber
- Comes in six rich colors

FAQ
How can I track my order?
Once your order has been processed and shipped, you will receive a tracking number via email. You can use this tracking number to monitor the status of your shipment.
Why does my tracking still show Pre-Transit?
No worries - this is very common and usually just means the postal carrier hasn’t completed the first scan of the package. Your order has already shipped out on our end, and tracking often won’t update until it reaches your local postal facility or goes out for delivery. This is a normal carrier scanning delay.
If it’s been 7 days since shipment with no tracking updates, feel free to reach out and we’ll be happy to help. We’re only able to contact the carrier once 7 days have passed.
Is it safe to shop on your website?
Yes, absolutely. We prioritize your security and use industry-standard encryption to protect your personal information. Your data is safe with us.
What is the estimated delivery time for my order?
Delivery times vary based on your location. Domestic orders typically arrive within 5-7 business days, while international shipments may take between 7-16 days. You will receive detailed delivery information in your confirmation email.
Can I use any type of cartridge with Smoke Empire Batteries?
All Smoke Empire devices are compatible with most 510-thread cartridges that are .5g-2g in size.
