Disappointed
I'm disappointed in the pouches because they are sealed very low on the pouch, which makes it difficult to open. It's like these are seconds. I've worked with this product for 6 months prior to buying them from Amazon. I've never had this problem before. There is a, tear here, cut on the package but it is sealed below the cut.
