Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid vs Lunch Food 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 Klean Kanteen.
• We flag Bamboo fiber lid degradation and microbial growth and Formaldehyde resins in bamboo fiber binder on the Klean Kanteen and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the Klean Kanteen is stainless steel with bamboo fiber 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.
