Drinking more water is easier said than done—but finding the right water bottle can make it more fun (and feel less like a chore). While there are lots of options out there, the TikTok viral Stanley cup continues to reign supreme for many hydration enthusiasts, including a few SELF editors.

Everyone knows that hydration is key – great for skin, hair and, of course, your health. But no one could have predicted Stanley cups going viral and becoming the IT accessory this year.

Stanley has introduced three new limited edition Midnight Glitz Tumblers, which are only available for customers for this holiday season. Given the popularity of Stanley products, many are curious about how to buy these tumblers.
