Glass Food Storage with Snap Lids vs. Stanley Quencher Tumbler

Materials

• Borosilicate glass
• BPA-free plastic snap lids

Common claims

• Oven, microwave, and freezer safe
• Non-porous glass
• BPA-free lids

Concerns / watch-outs

• Lids are typically polypropylene (PP) — avoid microwaving with lid on
• Glass can break if dropped on hard floors

Notes

Best practice for food storage. Glass body is completely inert. Just don't microwave with the plastic lid on to avoid leaching.

Cleaner alternatives

• pyrex glass containers
• anchor hocking glass

Materials

• 18/8 stainless steel
• polypropylene lid and straw

Common claims

• 40-oz capacity
• Keeps cold 2 days
• Dishwasher safe

Concerns / watch-outs

• The lid and straw are polypropylene — plastic in contact with your drink
• Past reports of lead in the base solder seal; Stanley confirmed and addressed this in newer models
• Verify current model status before buying

Notes

Very popular insulated tumbler. Interior stainless is safe, but the polypropylene straw/lid is a compromise. Lead solder concern was addressed in more recent production runs.

Cleaner alternatives

• klean kanteen bottle
• hydro flask bottle
