Wallaby Oxygen Absorbers are the essential companion for Mylar bags, ensuring your stored food stays fresh for decades. Available in 300cc, 400cc, and 500cc sizes, they are crafted from food-grade, BPA-free materials and carefully packaged in sets of ten to preserve effectiveness until use.

When combined with low-moisture foods like rice, beans, wheat, oats, powdered Milk, or freeze-dried meals, Wallaby Oxygen Absorbers can help extend shelf life up to 30 years. Perfect for emergency preparedness, camping trips, or everyday pantry organization, these absorbers provide reliable performance across a wide range of bag sizes: 300cc works best for quarts and pints 400 to 500cc fits 1-gallon flat or gusset bags Pair them with our Mylar storage pouches, label your bags for easy rotation, and have peace of mind that your food supply is secured for years.
