Listings commonly show capacities from about 16 fl oz up through 24, 30, 32 and 40 ounces, so you can find tumblers and bottles across those common volumes.
The listings mainly use stainless steel, with several explicitly calling out 18/8 stainless steel or recycled 18/8 as the construction material.
Listings commonly highlight leakproof or leak-resistant lids, locking lids or dedicated locks (for example push-button locks), and lid designs promoted to resist spilling.
Several listings note cup-holder compatibility or call bases “cup-holder friendly.” A few give specific dimensions—one listing, for example, lists a base diameter of 3.15 inches.
Warranties mentioned across listings include a 1 Year Limited Warranty, Lifetime Limited Warranty, and references to limited lifetime warranties.
