The Bluapple® One-Year Combo Pack contains a one-year supply of packets for the two Bluapples®. Each packet is designed to last about three months. The two Bluapples® inside the One-Year Combo Pack come ready to use. Just place a Bluapple® wherever you store produce. The remaining packets need to stay in the resealable package they came in or an airtight container. As long as they are kept in an airtight container, they will last indefinitely. Bluapple® slows down the ripening process by absorbing ethylene gas. By absorbing this gas, fruits and vegetables last longer, maintaining the nutrient value and taste. Ethylene is a harmless, odourless, and colourless gas that is given off naturally by fruits and vegetables as a signalling mechanism to the produce to ripen faster. This creates a high concentration of ethylene gas in the refrigerator, or other storage areas, which accelerates the ripening process and hastens spoilage. Using Bluapple® to absorb this gas causes fresher and longer lasting produce! Stop throwing away produce! Get Bluapple® today.
