I like to write on the back of my photos, but am having a hard time finding the right pen to use. Ball point pens poke through to the front. Some pens bleed through, and some are too wet and they smudge. Does anybody have any recommendations for a pen that will dry quickly and not do any of those things I mentioned? I tried a photo pencil from CM, but it doesn't work well and I want something fine tipped. TIA for any ideas!
