The Impulse Series is a sophisticated take on travel cups and will bring elegance to any promotional event! Each 27 oz. copper tumbler is vacuum-insulated, double-walled and made of stainless steel. Your drink will keep its intended temperature for a long time. Simply close the twist-on, slide open/close lid and take your drink with you wherever you go. After laser etching your logo on the container, give these to clients who will use it everywhere and get your name out there at your next promotional event!
