I thought I'd start a thread on this because I'm curious and still a relative newbie compared to some of you - Sorry if it's an old topic.
So what are peoples thoughts, most of my family and friends prefer postable pens (I think I was told that's the right term) unless its a ballpoint, but this doesn't seem to be the norm. I'd suggest there are slightly more non-postable kits...so my question is why and what are other peoples thoughts and experience?
