I really like the color and shading of Montblanc Irish Green. I also like its performance on poorer quality paper (from what I've seen in reviews). The one drawback is the $23 price tag which, as a high schooler, I am a bit hesitant to shell out. I was wondering if there are any similar inks out there with very minimal bleedthrough. Permanence or water resistance is preferable but not a must-have. I use a Jinhao with a fine nib if that is of any help.
Here is a writing sample from The Pen Habit, if you don't know what it looks like.
