The Boveda One Year Humidor Bag is the smart way to store your cigars when travelling or you can use it to condition new cigars. Each bag is made of an extra strong plastic that is considered three times stronger than a typical food storage bag. It is designed to provide the same protective moisture barrier as a tupperdor, but without taking up all that space. Its press-to-close zip top creates an airtight seal. Each bag comes with a 69% RH Boveda humidity pack so its ready to use. Available in three sizes: Small(5 cigars), Medium(10-15 cigars), and Large(50-cigars).
