This bubbler bowl slide has a built in ash catcher to help keep you bong clean. This comes in multiple colors so you match it up to your bong just how you want. the size for this is 14mm.
I love almost everything about his bong with the exception of the very small bowl which appears large but it has a very small interior space to fill.
Overall, I would recommend this bong to anyone!
We are glad you like the bong! Sorry about the bowl that comes with the bong, they do vary in size. We do have larger round bowls that hold more material.
