Effortless Craft Cocktails Make batches of handcrafted-quality cocktails in a fraction of the time.

Add fresh fruit, veggies, or herbs to the mixture, and the Aer disc will partially crush the ingredients, adding additional texture and bursts of flavor  BPA Free & Dishwasher Safe The container and lid are dishwasher-safe and made of BPA-free Eastman Tritan™.
