This is a great item for all the reasons already stated in previous reviews.

In addition, using this sturdy bag, and squeezing out the air prior to the final zip, keeps onions, garlic, tuna and cooked food items from crossing odors in your refrigerator.

Like any other plastic, it is best not to re-warm food with plastic touching the food in a microwave oven.

The next best use is to store those pictures that you cannot get around to cataloging or placing in photo albums immediately. They will stay smudge and dust free until you have time.
