These are made by Glad and Ziplock and I am having trouble finding them in my area so I'm afraid they may be discontinued. I've gotten a good lead from the LA board on laying my hands on some and note they are available at Drugstore.com, but I am curious if anyone else uses these? I ran out a few weeks ago and after steaming vegetables on the stove for a few meals I realize how sorely I miss the perfectly steamed produce that results. According to the package this method of steaming sans water preserves more nutrients. I wash and transfer vegetables to these bags upon purchase and they stay fresh for about a week until I'm ready to nuke. Have these caught on with anyone but me?
