Odor-proof, moisture-proof, etc. storage jars. They allow you to preserve food, herbs, coffee, flour, etc. in better conditions and keep them fresh for a few weeks. If you are going to store the product for 2 or more weeks, we recommend another type of product.

Note: this product is not a vacuum jar, that is, the oxidation process (degradation) of the preserved product continues even inside the jar, since its mechanism does not extract the air from inside the jar.
