I bought some new cel bags as it is time to rebag my cels, and I bought some online advertised as polypropylene 2 mil. Well, they arrived in a box, and unmarked so I'm wondering if you all could shed some light on these.
Basically, I wanna make sure they are safe for my cels. I do not want mylar. Have you all used any that look similar to these? Compared to my old cel bags, they are a little thicker, and not as clear.


Thanks all
