Product details describe these mini cans as carbonated sparkling water — the carbonation is listed simply as “Carbonated.”
The mini beverage cans themselves are shown as aluminum in several listings. In at least one description, the outer packaging or presentation is noted as paper or cardboard.
Some mini cans are labeled no added sugar or zero-sugar/zero-calorie. Reviewers of sugar-free or diet versions sometimes report detecting an artificial sweetener taste.
One product description explicitly states it is caffeine-free and zero calories. Most other listings do not clearly specify caffeine or calorie information.
Some listings indicate added flavors and vitamins alongside the sparkling water.
