Until I poured water into the bags thought nonsense. It turned out that does not miss the liquid at all, even if pressed. The only thing I thought would be a lock in the bags, it's not there. Closed only with a plastic lock
Very good product. THE silicone is very strong. Well sealed. THE smell is very strong, but put soak in hot water with detergent and left all the smell.
Packages arrived in a month, all different colors, close tightly
The pouch is excellent. I do not find the closure easy to use but everything is as described and correct
