It's not exactly a packer idea per se, but something that would be awesome would be a realistic strap-on (preferably with some room for the little guy too), uncut and with movable foreskin. I don't know if this would be impossible to make or not, but it would be incredibly cool if it could exist. It seems all the realistic strap-ons I've found so far have been circumcized, and as a guy who wouldn't have been circumcized it would feel a little odd to have a packer with foreskin and then losing the foreskin during sex. I know, it's a petty issue, but still.
