Mason Jar Vacuum Sealer Kit – Cordless, Regular & Wide-Mouth Jars, 10 Chalkboard Lids

How it works

One press pulls the air out of the jar

Air trapped in a container is one of the main reasons food goes bad. Cover your mason jar with its lid, put the sealer on top and press start. It sucks the air out of the jar and stops on its own the moment the jar is airtight, usually within 30–60 seconds.

• Airtight seals: the lid is pulled down tight onto the jar.
• Works on all mason jars: any regular or wide-mouth mason jar.
• Works with all canning lids: the chalkboard lids from the kit, or store-bought lids with the lid adaptor.
• Reseals endlessly: open, serve and reseal as often as you want, and reuse your lids.

Key features

Works with all store-bought lids

Quick, simple and easy. With the lid adaptor from the kit it seals the lids you already have, and the keychain lid opener pops the sealed lids open again when it's time to eat.

• Powerful: sucks the air out of your mason jars for an airtight seal, every time.
• Portable: use it on the go with all your mason jars as you open, serve and reseal.
• USB rechargeable: no batteries needed. The USB-C charging port works with all standard chargers, and a reversible cable is included.

Questions people ask

Can I use the mason jars and lids I already have?

Yes. It works with any standard regular- or wide-mouth mason jar, store brands included. Use the chalkboard top lids from the kit, or your own store-bought lids with the lid adaptor. If it has a lid, it seals.

How long does it take to seal a jar?

About 30–60 seconds per jar. Set it on top, press once, and it stops automatically the moment the jar is airtight. It's easier than screwing on a lid.

What foods can I keep in sealed jars?

Almost anything: dry goods like rice, flour, beans, nuts and coffee; fresh produce and greens; leftovers; homemade sauces, dressings and marinades. Leave about an inch (2.5 cm) of space at the top and it even handles liquids.

Can I use it for canning?

Canners often use it to seal the dry or dehydrated goods they keep in the pantry. It makes airtight seals for storing food in mason jars, but it is not a replacement for canning: proper canning needs specific heat processing to keep food safe.

How does it charge, and how many seals per charge?

It is cordless and recharges over USB-C with the included cable. A full charge is good for roughly 200 seals, so most households only charge it every few weeks.
