Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid vs MealBox Divided Glass Storage Container 5.5 Cup: which is safer?

Where these two actually differ

• We flag Silicone gasket degradation, Bacterial growth in vacuum seal and Surface corrosion under acidic conditions on the Klean Kanteen and not on the Pyrex.
• We flag Plastic lid leaching (BPA, phthalates, or other endocrine disruptors), Glass breakage and sharp edges, Seal degradation and lid fit loss and Microplastics from plastic lid wear on the Pyrex and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the Pyrex is borosilicate glass, plastic lid, which is most of the difference in these two grades.
