Is it just us, or have the 2020s been a different beast when it comes to buying water bottles? Those insulated tumblers we used to tote around at the gym have suddenly become *the* hottest accessory, and every other day it seems like a new brand is causing buzz for its beverage-cooling abilities—and/or similarities to the mega-popular Stanley Quencher. Given the fact that Stanley cups can be pretty pricey, savvy shoppers can't help but swoon over similar, more budget-friendly alternatives. Which is why Costco's Stanley lookalike tumblers have been going totally viral on TikTok lately. But here's a pro tip: You don't need to have a Costco membership to snag 'em, because we found the same ThermoFlask 32-ounce Insulated Straw Tumblers ($43), which come in a two-pack no less, at Walmart.

Similar to the Stanley in its design and construction, each 32-ounce ThermoFlask tumbler has a cup holder-friendly shape and is built with stainless steel and double-wall vacuum insulation, which the brand says can keep drinks ice cold for up to 24 hours. The cups also boast a wide mouth lid and come with two reusable Tritan straws (in both jumbo and standard size), as well as a splash-proof silicone gasket to prevent messes. The one feature that might make them even better than the Stanley, though? The grippy handles are conveniently removable, so you can switch it up as you please, or slim down the cup's silhouette for easy packing.

Reviewers note that the cups are durable and easy to clean (they're dishwasher-safe which is a big plus), but the real reason they've got everyone's attention is, of course, their price tag. Since the ThermoFlasks come in a duo-pack, you get not one, but *two* of these bad boys for practically the same price as a single Stanley tumbler. No wonder Costco (and Walmart!) shoppers are going wild for them.

Not sure about you guys, but we’re certainly not missing the opportunity to pick up these viral ThermoFlask tumblers from Walmart before more people catch wind of them.
