@vjgoh Eee. I've wanted to try Poussière de Lune at some point myself, but I don't have the budget right now, unfortunately. My current ink in that color range is Diamine Amazing Amethyst, which looks nice enough but seems to have some flow issues in the cheaper fountain pens I'm using.
@chalcedony so this was a gift, and I didn't even pick the colours. I'm so stoked.
But ALSO: one of the pens I'm using is a Jinhao x750. Got it off eBay for $3.50 cdn which includes shipping. Totally bonkers. And the pen writes really well! Stiff nib, no line variation, middling build quality, hard to post: who cares. Lays down a good line and I have no qualms about inking it up. :)
