stainless steel drinking cup

Reported retention times in listings vary: examples include hot for about 3 hours, cold for 8–9 hours, up to 40 hours cold, and in a few reports drinks stayed iced for as long as about 2 days. These are reported examples rather than guaranteed performance for every model.

Common lid types include slider lids, flip-top lids, drink-through or locking lids, and lids that include or accommodate a removable straw. Many listings mention one or more of these styles.

Care instructions vary by model: many list dishwasher-safe cleaning, some recommend hand wash or top-rack dishwasher only, and several specifically warn not to microwave. Check the product’s care label for the manufacturer’s recommendation.
