Received sample bags to test, so "GLAD" I tested them.  My first thought was how are these small bags going to hold anything.  I put them to the test.  I Started to clean out a storage room (one that we do not clean often.  I stared to put glass jars in one, aluminum in another and just plain garbage in the third one.  The more I put into the bags the more they expanded and best of all bags did not puncture!!!  You can bet these bags will go on my shopping list moving forward!!!!
