- Glass joint system eliminates paper from your smoke sesh
- Pre-pack all seven cartridges, be ready for anything
- Optional Filling System (not included) makes these a snap to pack

You dig the ease and portability of joints. You're not wild about the taste of burning paper. And you hate pulling out a joint just to find it smooshed and falling apart.

Solution: The GRAV® Fill-Your-Own Glass Joints 7-Pack.

This practical system marries the simplicity of the classic joint to the squeaky clean burn of glass.

GRAV® Glass Joints combine three individual pieces: a cannabis cartridge for flower, a glass mouthpiece, and a food-grade silicone grommet to connect the two.

Taste pure cannabis—no paper or glue with questionable ingredients. As you smoke your favorite flower, push the mouthpiece into the cannabis cartridge to ash and keep your herb in lighter reach.

This kit includes:
- One borosilicate glass mouthpiece
- Seven borosilicate cartridges for cannabis, with stoppers at each end
- One silicone grommet to connect mouthpiece and cartridge
- One tube container to hold it all

GRAV® Glass Joints are designed to last, but their low price point makes them easy to replace if accidents happen. Fill a single joint for an afternoon hike, or prep all seven for a weekend getaway. With caps on both ends and a dedicated carrying case, these joints are built for travel.

Each glass joint holds about half a gram of flower. Total capacity of all seven joints is approximately 1/8 ounce of flower.
