Materials

• 18/8 stainless steel

Common claims

• 40-oz capacity

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.
