If you are looking for something more functional than a regular thermos flask, you are in the right place. We offer innovative flasks with added electronics. Give your customers flasks that show the temperature of the drink on the lid, so they will always know if the coffee is still hot. For maximum brand exposure, engrave a battery-powered, illuminated logo on the bottle. Other options include vacuum flasks with an integrated wireless smartphone charger or speaker on the bottom. These are multifunctional solutions that your clients will definitely appreciate!
