Mingle with guests, or man the bar. What's a party host to do? Make batches of your signature cocktails beforehand with these smart, elegant bottles. The design is straight off Gatsby's bar cart, and on the back, laser-etched fill lines take the guesswork out of measuring ingredients. With drinks pre-batched and ready to pour, you might just get to enjoy your own shindig. Made from upcycled bottles in California.
