Good stuff
Size: 100 Pack
Excellent materials. As advertised-no surprises with finding stamped foil that doesn’t hold its contents. My wife uses these to bring food to my work and she is perceived as a professional chef.

Time saver!
Size: 100 Pack
I love these! They save so much time by making cleanup easy. The real messy ones just throw away, the not so messy ones go in dishwasher easy. They are so much better than lifting heavy pans out of the dishwasher. Also good for freezing meals then go right into oven! Thanks for such a good price on a helpful product!
