Tips for canning:
·Please store in dry environment.
·It is recommended that the time of Mason jars in high-pressure environment should not exceed 10 minutes.
·Before first use we recommend soaking in hot water to remove any impurities caused by transport and to soften silicone seal.
·When tightening the lid with fingers, it is not recommended to tighten it too tightly to prevent hot air from exhausting the Mason jars.
