What's cooler than being cool? Getting ice cold hits three ways with the GRAV® Glycerin Chiller Multi Kit. The superstar of this kit is the mouthpiece filled with glycerin, which can reach subzero temperatures without freezing. You can keep it simple with the taster attachment, which holds a small amount of plant matter and is angled for easy use. Or you can kick things up a notch and add the extra filtration of the bubbler attachment, which works best with about 0.5" of water. If you're a concentrate fan, the results nozzle is the perfect choice for you. No matter which attachment you choose, this kit includes a 14mm plastic clamp to keep everything secured in place.
