Common materials include stainless steel (often 18/10), and plastics such as ABS and polypropylene.
Capacities range roughly from 15 fl oz up to 26 fl oz, with common sizes including 15 oz, 20 oz, 24 oz, and 26 oz.
Insulation varies by model. Several insulated tumblers list hot retention up to about 12 hours, while cold retention is commonly in the range of roughly 24 hours to 30+ hours depending on the design.
Care varies by model: some listings state dishwasher-safe (often top-rack and in a few cases up to many wash cycles), while others recommend hand washing. A brush is often recommended for cleaning straws and narrow openings—follow the manufacturer’s care instructions for best results.
Kid-focused listings include age guidance (for example, recommended ages 3+), leakproof silicone or valve-equipped straws, screw-on lids, and designs that disassemble for cleaning; some are also labeled dishwasher-safe.
Fit depends on the model. Many tumblers have a tapered or slim base designed for vehicle cup holders and are described as fitting most standard-size cup holders; exact fit varies by design.
