Reusable Platinum Silicone Storage Bags Stand Up Dishes Zip Lock Food Containers, Set of 3

These "Reusable Platinum Silicone Storage Bags" are useless. The zip closure worked at first, but now is impossible to close. I can't tell what changed. The silicone material feels great and the seal appears robust to the eye, but they no longer seal, after very few uses. And the seal failure applies to every bag. Go figure.

1st use ok, bags won't hold closed, useless.
