Food Grade & BPA-Free Materials - Made with food-safe, BPA-free materials for safe use with dry goods. Compatible with Mylar bags, mason jars, PETE bottles, and buckets—great for home storage or emergency kits. 300cc Oxygen Absorbers (120-Pack) - Includes 120 high-performance 300cc absorbers, vacuum sealed in 12 packs of 10. Keeps rice, beans, flour, coffee, and spices fresh by eliminating oxygen. Color-Changing Oxygen Indicator Included - Comes with an easy-to-read oxygen indicator that changes color to confirm freshness before use—no guesswork, just confidence. Individually Vacuum Sealed in Packs of 10 - Each 10-pack is vacuum sealed to protect performance. Use only what you need and keep the rest safe and effective. Important Usage Note - Oxygen absorbers remove only oxygen (about 21% of air), not all air. That means bags won’t shrink like vacuum-sealed pouches—this is normal and expected. A slight warmth during activation is also safe and harmless. Quality Food Grade Oxygen Absorbers - Our factory holds ISO 9001 certification, and our oxygen absorbers are made of premium quality food-grade materials.
