Review on Industrial Plastic Reclosable Resealable Zipper by Tyler Cooley

These sachets are not 4 mil they are 2 mil I will be returning them for a refund due to mis-advertising. Maybe it was a mistake, but I doubt it. Most people wouldn't question the thinness of plastic like I did. So I got my electronic caliper/micrometer and measured a few. I do not recommend them to anyone who wants or needs 4 mil bags from this supplier. I will wait a few days to see if the seller will contact me and offer a solution.
