Where these two actually differ
- We flag Bisphenol A (BPA) or BPS in polymer blend and Microplastic shedding on the Marshall and not on the Pela.
- We flag Bioplastic thermal degradation and oligomer leaching, Microplastic fragmentation during use and disposal and Composting infrastructure dependency on the Pela and not on the Marshall.
- The Marshall is Plastic earbud case (polyurethane or similar polymer) where the Pela is Plant-based bioplastic, compostable polymer, which is most of the difference in these two grades.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
