The LaVoo Downstem/Bowl combination is for the LaVoo MP1, MP1XJR, & MP7 models and fits without the need of rubber grommets. Like all LaVoo bowls, this is a funnel style bowl which allows for more flavor.
I believe I bought the wrong size for the type of hookah that I have but I made it work. Overall, I am satisfied with the service and product. I am definitely going to be a patron of your business. Thank you
