The CoffeeVac is a storage container that features a unique patented vacuum closure system. It's perfect for storing coffee beans and tea leaves. The CoffeeVac is able to preserve coffee beans for long periods by allowing products to breath and degas. It features a 2 way valve which allows the carbon dioxide from the beans to slowly escape, without letting oxygen in which is why it can preserve goods for long periods of time. The CoffeeVac saves you money by keeping your coffee fresh for longer and the 2 way valve never needs replacing. In addition to coffee or tea, the CoffeeVac can also be used for other dry & wet goods. Available in Black or Clear Tint in 250g, 500g or 1kg capacities.
