Thank you my friend. I think it is the most appropriate. It's a good tool, so I don't break my wrists or even burst the jar and cut myself. But I'm not kidding when I say, with Teflon, the seal is a rock. They take I think three years, and it's impossible with my strength and big hands, to open the jars. Maybe this teflon is a good idea, in the long run, but I only have three years of proof of this kind of packaging. It was a novice experiment, when I started to wrap my first pipe tobaccos.
