Prime Hydration fans on social media have been left confused after they have begun to spot subtle differences on the shape of their bottles.
Those who have been purchasing the viral sports drink recently have been noticing that the bottles are now made with a heavier plastic and have a different base shape.
BirminghamLive reported that many fans have taken to Twitter to express their suspicions over the difference, with some suggesting that it is a way to "spot fakes." However, the slight change in the bottle packaging may be down to a more simple reason.
