How to Use
- Put the mason jar lid on top of the jar (Not suitable for one-piece lids with rings)
- Press the sealer down firmly, holding it smooth
- Remove the top mason jar sealer to double the effect by adding a ring lid (ring lid not included in our package)
Why can't it be sealed?
- When filling soft or liquid food, do not overfill the bottle, the less air in the bottle, the longer the sealer will work and the sealing effect will be short.
- Please check whether the mouth of the mason jar is dry and clean. If there is water or debris at the mouth of the bottle, the mason jar sealer will not be able to seal.
- The mason jar vacuum sealer did not press into place and did not allow the mouth of the bottle to fully enter the sealer.
- Mason jars don't match the lids.
