Whether you prefer to sip your drink slowly or quench your thirst in larger gulps, the tumbler's convenient design makes it a versatile companion for work, meetings, fitness, or travel.

Available in 9 different colors, the tumbler is enhanced with a sparkling powder that adds a dazzling touch, catching the sun's rays and creating a visually appealing effect.
