This is one of my newest favorite products! Easy to fill, smoke hit nice and cool yet didn’t mess with the flavor or high. @trees

Having a hard time telling how this works. Does it hold a joint or just like a bowls worth of weed? Do you smoke right out of it or does it hook up to something?
- The silicone piece allows a glass plunger that is also a mouthpiece to basically be pushed forward slowly letting out more weed
- The reviews have pictures here that show it in use. I was also confused until seeing them in action https://grav.com/products/grav-fill-your-own-glass-joints-7-pack
