NWT Starbucks x Sofie Birkin 24oz Rainbow Studded Tumbler

The 24-ounce studded plastic cold cup tumbler features a double rainbow – with both a vibrant spectrum of color on the cup’s exterior and a swirly rainbow straw on top. Birkin’s playful cupid on the back adds a touch of whimsy to the design. “I’m just such a romantic,” she said. “I love that kind of thing.”
