We use your H1 Bell Hammer product. We’d like to repackage some grease into standard polystyrene containers as accessories. We believe it’s fine, but are there any known issues with polystyrene?

Regarding the use of polystyrene containers for small packages, we believe that under normal conditions of use, there will be few major problems.
However, polystyrene is a material that can swell or crack when exposed to solvents or oils, and long-term storage or high temperatures may have an effect.

Therefore, the following precautions should be taken:
*For short-term use, there is generally no problem.
*For long-term storage, we recommend that you consider more chemical-resistant materials such as polyethylene or polypropylene.
