Kids Insulated Reusable Lunch Box - Skateboards Later Skater vs Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid: which is safer?

Where these two actually differ

• We flag Microplastics from plastic degradation and Bacterial or mold growth in fabric lining on the Contigo and not on the Klean Kanteen.
• We flag Silicone gasket degradation, Bacterial growth in vacuum seal and Surface corrosion under acidic conditions on the Klean Kanteen and not on the Contigo.
• The Contigo is plastic exterior, fabric interior lining where the Klean Kanteen is Stainless steel body, silicone gasket lid seal, 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.
• We are less certain about the Contigo grade, at 45% confidence against 82%, because it discloses less.
