The air up® Straw is a reusable straw designed to bring scent-based flavour to any glass, mug, or bottle, without needing an air up® bottle. How it works: Just place a flavor pod on top of the mouthpiece until it clicks into place. That’s it, no buttons, switches, or activation needed. The flavour is always active while you sip. You’ll feel small bubbles while drinking—this means the retronasal magic is working 🫧 It’s a perfect way to try air up® without committing to a full bottle 👀
