You mean put the foil inside the pen too? how would I do that?

Or do you mean, just put it around the outside, and fold the excess into the pen?

yeah yeah how you said it. Like the foil doesn't have to go all around the pen eaither. It just has to go around the top kind and you fold some so it goes insidde the pen.
