Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid vs Meal Box Glass. 3.8 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 Snapware.
• We flag BPA/BPS in plastic lid, Phthalates in plastic lid, Plastic lid degradation and leaching and Microplastics from lid wear on the Snapware and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the Snapware is borosilicate glass with plastic snap-lid, which is most of the difference in these two grades.
• The gap is 30 points, wide enough that this is not a close call, and the Klean Kanteen is the one to buy.
