Nice Diversity of ink. A few that I have tried thus far are a bit too pale for needs. Otherwise, I like the idea and look forward to using different ones.
I buy this as a gift to myself every year. If you are new to pens or have been around them forever, I can't think of a better way to get a massive sample of great looking inks. It contains varied types including shimmer etc. An excellent value considering you end up with over 300 ml of ink. I have these calendars from the last 3 years and now have a ridiculous palette of colors to choose from when I get ready to write.
