Do you have or know of a site that should be listed here? Please let me know. I have certain requirements to be included. Your site must be primarily devoted to pens, pencils, inks, or products related to those items. I request a reciprocal link to this site from a link that is obvious on your site. I will list sites without a reciprocal link for a fee but I cannot guarantee that you will get any traffic. I will list all important sites with or without a reciprocal link if that site is important to the hobby of collecting and or using pens.
