Winsor & Newton Calligraphy Ink (Red Caps)

I am left handed and hold my pens in an unconventional, overhand grip. This limits a lot of my writing to fountain and broad edge pens only because my pen angle is too steep for dip pens. I always wanted to use a white ink with my fountain pens for dark envelope addressing, but there was never anything I could find that seemed promising. All the great white inks calligraphers suggest are for dip pens which are not an option for me. This white ink works so well and still has great coverage without feeling opaque. I found that mixing 2:1 ratio, 2 parts ink with 1 part water, gives great viscosity while allowing good flow from the converter. The other great thing about this ink is that it dries super fast which means you can write without your hand smearing the ink. Even with my hand running across the page, there is no white residue that smears onto the parts my hand is resting. The only drawback is that the ink does dry out on the nib after a period without using or putting the cap on to use later on. I found that quickly dipping the nib in a small amount of water gets it back going again. I tested this ink on a cheap fountain pen and I likely will only use this ink in a cheap fountain pen given the characteristics. I have included a link below that shows writing examples for you to view. https://www.dropbox.com/scl/fo/bj4ducnxwwee4mldh9hel/h?dl=0&rlkey=b4x3vemw8qmvpgc0w49hl98hj
