What do you put your foil and other cards that are prone to scratching in?
 

The card savers and even some of the thicker top loaders are tight enough
that they have enough resistance that they can scratch or chip foil cards
and cards with black borders.

Penny sleeve + top loader = safe and sound .


Added security put that in a team bag and close it tight.

I just open the CS1 wide enough so there's no resistance. It's more art than science as you have to open it wide on the initial entrance and then lightly close it on the final part. I haven't caused any damage... yet. Knock on wood.
