Krave Glass is a high-end scientific glass and grinder producer that pumps out nothing but eye-catching pieces and tough yet stylish grinders. Since 2010, Krave has made a name for themselves producing freezable glycerin pipes and bongs that produce freezing cold smoke to make your next session an even better one. If you don't want to freeze an entire piece, they also make freezable bowls and downstems that freeze quicker and still produce a colder smoke. Aside from the glass, Krave is also known for its heavy-duty grinders, all of which have four chambers, strong sharp teeth, and a pollen collector.
