These are very good bags. They hold up to 6 oz, but I've always put 10 oz in each bag, and while I did have a couple (about 5 in the span of a year) that had a hole in them when I went to defrost, I'd say that's a small price to pay. Mind you it was entirely my fault they had holes because I was putting too much milk in them.
