These things were horrible from this vendor. I know its impossible to know on a blind shot. but dude, these bags were like vacuum sealed together. I had to peel open each envelope. Huge paid in the neck. You should be able to just open it and insert whatever you put in.It was so annoying, I would literally get the blow gun on my air compressor and blow air into about 20 or so at a time just to prep them for use.
