Heat-resistant plastic, washable and reusable, not easy to scratch cans.
The package contains: Red aerator x 1 Green aerator x 1.
Marked with a measuring ruler, it is convenient to measure the top space of the can and effectively remove air bubbles embedded in the food in the can.
To ensure that there are no air bubbles in the tank, run the deaerator on the edge of the can and gently move the can to release the air inside the tank.
After removing the bubbles, you can add more food to the tank as needed.
