my local art store had like 30 of them on a shelf so i racked like 10 of them, I must say these are the shiznit. I filled em up with my own ink and they get maaaad juicy, just take some of the cotton sh*t out first.
Theres a video of these on you tube, just search K-66 and click on the first one, it should be from "thebombshelter" no doubt about it I'm gettin one of these, they write like dalos but it looks like they mixed the dalo ink with..well...ink. It's sooo nice and drippy. very opaque. I 100% reccomend these
P.S. Itr sucks to ahve to wipe the tip after every use.
