Just wanted to let people know that the previous review is correct; These sheets are not as thick as those of 10 years ago. I know because I still have some of the old ones! I don't think it's half as thin as the previous version because I suspect a microscope would be needed to pinpoint that. I would have preferred the same thickness as the old version, but since I don't plan on tearing a double-sided laminated item in two, it will probably be fine. My biggest concern is that it will stay just as waterproof; which probably has more to do with the glue and the size of the rim than the plastic itself.
