Never mind why I need these, lol. I just do. Uhm...science experiments. Yeah. Let's go with that! I am hoping to get recommendations for readily available a pen under $20 that takes standard international cartridges, is NOT made of metal, and is a wet writer. Slim pens don't suit me either. I am absolutely, definitely, moving away from metal-bodied pens and will be doing a couple of PIFs in a while. I already own a Kaweco Sport and four Nemosine Singularities. The Nemos fit the bill but write dry and need fiddling. There's my Rotring Core...wouldn't mind another (XL this time), but the prices have gone through the roof. Any other suggestions? Thanks!
