The EVAK glass storage containers store your food by removing the air. Most glass containers are already sold with air-tight lids however, they still trap stale air in with your delicious food. By removing the air automatically, your food is kept fresh and will last longer without getting stale.
The built-in twin valve system forces the air out as you push down the lid, then lets you easily pull up and remove the lid. There are no buttons -- just simply push the lid up or down for easy access. It works very fast and efficiently without any hassle when storing your food. For those food lovers who always want to keep their food fresh in the kitchen, air removal storage containers are the best holiday gift idea.
