I stocked up on Deleter ink recently. I love Akadot! Prices are good and they ship fast. I ordered it Wed and it arrived Sat, and they're in CA. I splurged and also got the pen nib assortment that comes with a free nib holder, which seems the perfect size. Most are either too long or too thin.
My good pal Andy Fish turned me on to Deleter ink and it really is the best. It's not watered down like so many of the other inks. It creates a beautiful saturated black. I like Black #1 in the purple bottle.
