content: We are trying to rid our lives of all plastic, whether BPA-free or not, but bought these well before that change. They seem kind of cheap, but do function ok, which is why I gave them two stars instead of one.THE LABELS WEAR OFF EVEN AFTER A FEW GENTLE HAND WASHINGS. I never sent them through the dishwasher, and was careful not to scrub the size labels at all, to no avail.I would spend 5 more dollars and get some stainless steel ones. In fact, try to convert all your kitchenware into Pyrex glass, stainless steel, and bamboo. You won't regret the quality or the health benefits.
