Love the colors

These are my pen of choice. I like the flow and depth of the ink. The ink is also consistent and only rarely is it blotchy. The ink of the first box of pens I bought lasted for several months, but the second box I bought had a few duds - they only lasted for a couple of weeks before I had to switch pens. I guess it's hit or miss, but if you get a good box, you're good to go!
