I'm writing daily with my ink pen (Montblanc 149) for my job. After trying several types of ink, I came across the Private Reserve Midnight Blues (most beautiful color), first the regular one. Ink flow fits to my normal writing speed. As I'm lefthanded it smeared if I did not pay attention. The Fast Dry solved the problem! Since about 5 years I'm using the Private Reserve Midnight Blue(s) Fast Dry ink and I'm not going to change. As it is hard to get in Germany, I thank THE GOULET PEN COMPANY very much to ship overseas!!!
