This lid is designed to securely snap onto your Mini Meat Lug, ensuring safe and easy transport from processing to the kitchen. It also provides stackable storage, making it ideal for organizing items in your refrigerator or freezer. While it fits securely, it does not create an airtight seal, allowing for ventilation as needed. Please note, this lid is specifically for the Mini Meat Lug and is not compatible with other lug sizes or the previous Mini Meat Lug (SKU 1572).
