The narrow-mouth jar sealer works with FoodSaver vacuum sealer systems to keep goods fresh longer. Great for
liquids, fragile foods and dry goods like brown sugar, spices, dried fruit and coconut. Sealers create a vacuum seal that
locks out air, the enemy of freshness. Air is quickly and easily removed, maintaining long-term freshness. (Wide-
Mouth Jar Sealer shown.) Not to be used for canning.
