HI Lou I think it depends what i'm journaling to be honest. I never use the original photo's so making the pens acid free never worries me that much. I usually print off the text on the computer or use a gel pen. I have bought 'Gelly Pens' before and they are really good, like gel pens only wetter and runnier, they don't runout half way through a word

. It says they are ok for scrapbooking. My white one is a God send!
