Wine Mummy is a protective bag that will prevent your bottle of wine from breaking in your luggage and all over your clothes. It is a must have if you are visiting wineries via air travel. The Wine Mummy is made of a tough plastic filled with multiple layers of bubble protection. The Wine Mummy seals at the top of the bag, preventing leaks if your bottle does break. It is also re-usable! Keep it with you luggage so that you will always have a way to take that special bottle of wine home. With the FAA restrictions on liquids in your carry on, this is the best way to protect a bottle in your checked baggage.
