Lunchbox, Aladdin Metal Latched, Top Compartment Holder, Black Handle, Vintage vs Lunch Food Box: which is safer?

Where these two actually differ

• We flag Lead in enamel/paint coatings, Aluminum leaching from bare metal exposure, Coating degradation and microflaking and Bacterial growth in latches and crevices on the Aladdin and not on the Klean Kanteen.
• We flag Bamboo fiber lid degradation or contaminant absorption, Gasket or seal material composition and Bamboo fiber formaldehyde or chemical treatment residue on the Klean Kanteen and not on the Aladdin.
• The Aladdin is Metal (steel/aluminum) with interior enamel or paint coating 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.
