For those who love smoking out of water bubblers and bongs, you can truly never have too many bowls in your possession. Glass can break at anytime, especially when extremely hot temperatures are involved. Ooze flower bowl slides are incredibly affordable for the quality, so stock up and keep a few quartz glass bowls in your stash. Quartz is the ideal material to use for bowls and accessories. It handles heat well, heating up fast and cooling off quickly. This bowl has a 14mm male connection, making it compatible with any bong with a 14mm downstem.
