As a last resort, I have had great success taking off labels by heating them a little with a hair dryer. Doesn't take a lot of heat to loosen the glue. Maybe make a mask with cardboard so you are only heating the label. Have patience and pull slowly. I would practice on some other labels first to get the swing of it.
I tried to remove the label and could not do it without greatly stretching and distorting the thin bag. When I told Chris at Superformance about this he quickly shipped out another one without the label. Let Chis know your issue. He told me that he is no longer attaching labels to these fragile bags.
That would be my instagram. I had it in my signature as there is a lot of things to see which aren't on the www. But apparently, that's not done over... ♂️
Sergio, I do not think that is a very kind reply. What have you supplied to the Dino world? Regards, Alberto
