I have a set of gel pens with lots of pretty colors that I'd like to use. Plenty of ink in them, if I could just get them to work. Help?

I've been drawing anime for some years now, and I've always admired the really smooth work that professional artists do. I've tried Sakura Pigment pens, but the nibs get worn down really easily and the pens don't have that "smooth" quality to them that I'm looking for. I'd like to find a pen that would give me the best quality of manga. Preferably, these pens should come in a wide variety of sizes (from about .005 to whatever). Thanks!

I am a small business owner, and I am wanting to get some promotional pens/pencials, but I am on a tight buget where I cannot spend $100 on pen with my imprint. I have looked into many different promotional pen places, but they are all too expensive. I have some of my own pens that are completely blank and I like them. How would I go about imprinting my own logo on them? I have tried to use clear address labels, but when the label gets wet, the ink runs....Any suggestions?

I have several boxes of gel pens which are brand new. Many of these pens do write. They have plenty of gel and may write a character or two...that's it. How do I get the gel to flow?
