Tumblers & Water Glasses by STANLEY. Details:For short commutes, quick errands, or just hanging out at home—say hello to our smallest and lightest Quencher. It’s also perfectly sized for kids’ use during the school day, at the playground, or bedside. Fill this 14-oz tumbler with water or your favorite iced coffee or iced tea. Whatever your beverage preference, the vacuum insulation will keep things at the ideal temperature while you hydrate or caffeinate. The lid features a rotating cover with three positions: an opening for the reusable straw, an opening for sipping, and a full-cover top to prevent splashes.
