I've been using these steaming bags for years. We steam large batches of corn on the cob in the summer, and the bags are durable and thick enough that I can use one for several batches of corn. The size is large enough that it will hold 4 half ears of corn. I also use them for broccoli, cauliflower, baby carrots, zucchini, and just about any other fresh vegetable I buy. It's good for quickly steaming shrimp as well. I have a hard time finding them in stores anymore, so ordering them in bulk not only saves money but I can have them several packs on hand as I go through a lot of them.
