Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid vs Lock&Lock Dosilock 3 Layers Multicolor Lunch Box Set Starter Pack with Spoon Chopsticks: 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 Lock & Lock.
• We flag Microplastics shedding during heating or mechanical wear and Bacterial growth in seals and gaskets on the Lock & Lock and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the Lock & Lock is Polypropylene (PP) plastic containers with stainless steel utensils, 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.
