First, I apologize for my poor (out of practice) penmanship.
I mentioned the ink used, but forgot to mention the color. It's black (rather obvious, but I wanted to mention it). This pen is just like the one I used in my second grade penmanship class, I lost the pen years (decades) ago.
I decided to try to find a replacement on eBay and found one still on the card, I'll admit that I likely paid more than I should have but it IS just like the one I used in school.
Here are a few photos.
