I paid AU$17 for this, and later saw it on sale at Singapore Changi airport on sale, buy 2 for $8 each or something. I compare it to the much cheaper Daiso pens I got for AU$1.40 each.
It is heavier and sturdier than a Daiso pen.
It is more comfortable to hold than a Daiso pen.
It has darker ink than a Daiso pen.
Comparing all these pens side by side, it doesn't look worth it's price to buy fancy pens.
When I carry it around (after all, it's purpose is to be portable), I find that I'm terrified of losing it!
