30oz Stainless Steel Handled Tumbler 2pk Lemon/Blue Stripe vs 20oz TKWide with Café Cap, Tofu: which is safer?

Where these two actually differ

• We flag Lid or handle material composition, Bacterial growth or biofilm in seams and Nickel sensitization from stainless steel contact on the Ello and not on the Klean Kanteen.
• We flag Powder-coat cap degradation over time, Bacterial biofilm in cap threads and seals and Thermal stress on seals at extreme temperatures on the Klean Kanteen and not on the Ello.
• The Ello is Stainless steel, no disclosed coating or treatment where the Klean Kanteen is Stainless steel bottle, stainless steel cap, which is most of the difference in these two grades.
