Enjoy more tea on the go with our new 17oz travel infuser. Its double-walled stainless steel construction will keep your tea quite hot (or cool, if you prefer) for hours. Spring-loaded lid opens easily with just one hand, allowing drivers to keep the other safely on the steering wheel. Sliding easy-click lid-lock prevents accidental openings. Fits most car cup holders. To use: fill three-quarters of the way with water (water line below the removable stainless steel infuser) and place leaves inside the infuser basket. Flip the unit upside-down for a thorough, flavorful infusion. Once infused, flip right-side up to separate spent leaves from water and prevent your tea from turning bitter. Travel far and wide with quality freshly-brewed tea! Please note: This tumbler is exceptionally well-insulated, with a vacuum-tight seal. It will keep your tea very hot, sometimes for several hours. Please sip carefully to avoid burning your mouth! In addition, be sure to open the cap away from your face when tea has been steeping, to avoid any escaping pressurized steam.
