Stainless Steel Skinny Insulated Tumbler Cup with Lid and Reusable Straw vs 20oz TKWide with Café Cap, Tofu: which is safer?

Where these two actually differ

• We flag Plastic lid/straw polymer identity and leaching (non-BPA), Lid gasket and seal material unknown, Bacterial or mold growth in insulation layer and Thermal stress on plastic lid during hot liquid use on the Cupture 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 Cupture.
• The Cupture is stainless steel tumbler, BPA-free plastic lid and straw where the Klean Kanteen is Stainless steel bottle, stainless steel cap, which is most of the difference in these two grades.
