The Stanley x Barbie Collection has been dropping all week and you can finally get your hands on the coveted '80s Western Ken design but only if you hurry. Here's how.

Stanley has teamed up with one of the most iconic personalities of the century: Barbie. Every day this week, from Monday, September 16 to Friday, September 20, the viral drinkware brand is releasing new tumblers from the Barbie x Stanley collection.

Stanley cups fit in car cup holders despite their large size and have a straw that makes staying hydrated just a little more fun. The viral version of the Stanley cup is the 40-ounce model, likely because drinking two of them almost equals the suggested daily water intake for women, taking the guesswork out of drinking enough water each day.

In honor of Barbie’s 65th anniversary, the beloved drinkware brand is launching a core capsule of Stanley Quenchers sporting everything from the iconic 1959 original Barbie to an ’80s western theme for Ken.

This is not a drill! You can buy the entire Barbie x Stanley collection today — yes, today! For those obsessed with the dolls who do it all, collect Stanley cups as if it’s nine to five, or both — this is one Quencher drop that simply cannot be missed.
