Last night I Inked up my Nahvalur Original Plus (my fancy pen) with Diamine 150th Anniversary Tropical Green. So far, I love this ink, the pictures don't quite do justice to it's vibrant and velvety color. I bought it because MountainOfInk reviewed it as being well behaved and drying quickly, which is exactly what I need because I use this pen to take notes when I'm home (it's too precious a pen for me to take with me). Anyhow, if you need a Christmas ink, I might suggest this one.
