@NeverBend , when ever I have received a package of pipe tobacco in regular ziplock bags, it is immediately evident from the smell. Generally the box will smell great , even after being emptied. No smell on the outside of these bags. One you sent was a ziplock type with the tear open spots. It did tear open where it was supposed to. I took the tobacco out and jarred it. Since then I have opened and closed the bag several time. It works great. One time I closed it, puffed up slightly, with some air in it. Squeezing will not make it pop open. I finally was able to squeeze the air out, but it was incredibly hard. After that, I opened it backup and put some water in it. It held. I had to really give it hell to make it leak. It took a lot more pressure and manipulation than it should ever be under in normal use. These are great.
