My point when I talk about why I don't use these pens is NOT that I'm going to be putting them in the freezer. It's that there is obviously some sort of substance still in the fabric if the lines come back at a certain temperature!
I found these pens several years ago at a show, and did research on them back then. Pilot manufacturers them, so I contacted their customer service and at that time, they were NOT made with archival ink. So I made the decision to stick with products that are specifically made for marking - and disappearing from - fabrics. I think the Frixxion pens were a happy accident for Pilot, and now that they see a secondary use for them, they're happy to market them to quilters.
