One for you, one to share. With the Legendary Classic Buddy Cups, you can easily take two insulated cups along with your favorite Stanley bottle. Whether you're taking a walk in the park on a cool day or heading out on your next camping or fishing trip – you'll always be ready to toast with a warm drink for both of you. They fit all Legendary Classic Bottles, available in colors that match your bottle or for a fresh look. With a screw system, both cups can be securely attached to your bottle until you're ready to pour. When you're ready, simply detach the cups, fill them from the bottle, and enjoy your drink. Cheers!.
