The majority of bong specification sheets are sales summaries wearing a technical costume. This guide recognizes the measurable fields wholesale buyers need to call for before authorizing glass bongs for manufacturing, import, or retail.
Most buyers do not lose money because glass is bad. They lose money because they guessed the joint size, ignored joint gender, or forgot the downstem entirely.

This guide breaks down bong joint sizes, bowl slide sizes, and ash catcher standards with a blunt, buyer-first lens.
