Easily tame your adventurous spirit with the 360° Traveler SONOMA! Its double-wall vacuum insulation and leakproof 360 Lid make it a cinch to use - just press the button, sip from any side, and press again to close. Spot the subtle indicator line to know if it's open or sealed. For best results, remember to give it a wash first then clean under the center button by hand with a brush. Lid top-rack dishwasher safe. No disassembling, freezing, microwaving, bleaching, or overfilling allowed. Heads up: Liquid can gush out of any side when open, so be wary of hot liquids and keep closed when not in use. Not ideal for carbonated drinks. Ages 3+ only.
