ONE-TOUCH AUTO STOP SEALING - Place the sealer over the jar lid and press the button once. The M12 automatically completes the vacuum cycle and stops in approximately 25–30 seconds, eliminating repeated button presses, manual pumping, and constant timer checking.

FITS WIDE AND REGULAR MOUTH JARS - Designed for the Mason jars already in your kitchen. Use the main sealing area for wide-mouth jars or install the included adapter for regular-mouth jars. One compact electric jar sealer handles both common jar sizes.

2500mAh RECHARGEABLE BATTERY - The built-in high-capacity battery can seal approximately 250 jars on a full charge under normal operating conditions. Its cordless design is convenient for weekly meal preparation, pantry organization, bulk food storage, RV trips, cabins, picnics, and camping.

STORE EVERYDAY FOODS WITH LESS AIR - Remove excess air from compatible Mason jars containing coffee beans, loose tea, nuts, cereal, rice, pasta, flour, sugar, dried fruit, herbs, spices, baking ingredients, cookies, candy, snacks, and pet treats. It can also be used for refrigerated salad jars, opened jam, and prepared ingredients.

COMPLETE MASON JAR SEALER KIT - Includes one M12 electric Mason jar vacuum sealer, five wide-mouth jar lids, five regular-mouth jar lids, three sheets of writable food labels, one USB charging cable, one jar lid opener, and one user guide. Mason jars are not included.
