How to open the jar?

The jar is very well sealed, and airtight. Find below the methods that facilitate the opening:

  1. Pour warm (room temperature) water on top of the lid, for a minute. This will increase the pressure of the air inside.
  2. Open the metal clamp.
  3. With a dry tissue for a better grip, pull the silicon tongue of the joint.

In addition:

4. Insert a round knife, or a butter knife (one that will not hurt you) between the joint and the lid. Once well inserted, rotate it slightly or use it as a leverage, to allow some air to penetrate the jar. Once you hear the sound of air suction, the jar will open by itself.
