I bought my daughter a set of multi-colour Bic Cristal pens and, aside from a weird plug that had to be removed from each tip (intentional? dried-up ink from the manufacturing process?) the textural quality of the ink is wonderful. I don't know what it is or how it's different from normal Bics but they are a pure joy to write with.
So I bought myself a set and now write in pink at work... .
Yes, the "plugs" on top of every tip of pens are very much intentional.
They are found on every new ball pens and refills in India. I don't know the exact purpose of their existence, but I guess it has to do with leakage of ink.
I never thought I would see this question here! I now write with FPs exclusively, but removing those beads from newly bought pens were special experience to us as little kids! We fondly associated them with the joy of new pens. We used to call them "pearls".
