Gamma Lid - White

I have used more than 60 gamma lids and ordered many more for my friends' use. I have never seen a broken lid, but have destroyed a lid through dropping and breaking a full bucket. I store dry foods with oxygen packets very successfully over the last 5 years, losing nothing. I store wheats, corn, white rice, beans of many types, sugar in original packages,flour, bags of dry milk, hard chocolate and cake mixes still in their plastic bags with one original box emptied and packed with the recipes included. I am glad to have discovered these gamma lids. Storing dry foods has become easier and better organized.
