We are most exposed to the issue of size grammage of round bath bombs in our daily follow-up process, for which we have prepared a size and grammage match table to facilitate you to understand it at a glance.
Notes:
- Due to the different production processes, the gram size is not precisely the same in each factory, but similar. In other words, these parameters are not standard.
- Depending on the fizzing effect, the parameters vary but are similar.
- For the same size, the sinker is heavier than the floater.
- Since they are handmade, there will be errors in gram weight, so you will see that the same size can have different grams (but close).
