reusable to go cup

Reusable to‑go cups range from small toddler sizes to large tumblers. Common capacities include 7 oz, 10 oz, 16 oz, 30 oz, and 40 oz.

Cold retention varies by model and insulation quality. Typical listings show ranges around 9–11 hours up to roughly 24 hours, while some insulated tumblers report much longer retention (around 40 hours) and a few listings note "2 days iced." Actual performance depends on the cup’s design and conditions.

Many designs include carry loops or handles and base shapes intended to fit most cup holders; some listings note cup‑holder compatibility or provide a base diameter for fit.
