Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid vs 12 Can Dual Lunch Box: 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 Thermos.
• We flag BPA/BPS and phthalates in plastic lining, Foam degradation and microparticle shedding, Bacterial or mold growth in insulation and Metal lining corrosion or coating wear on the Thermos and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the Thermos is plastic exterior, foam insulation, metal/plastic lining, 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.
