Idk what it is about them...I like Royal Dragon the best so far but its becoming hard to find

idk   

never heard of royal dragon   

i did hear that kuro sumi has a line of colors out but ive heard only negative things on those i havent tried them out yet but might pick some up

starbright for me never had a problem. kumo suri  for black. i tried moms but just wouldn't work for me.

royal dragon is a cheap ink

Fantasia, some starbrites, waverly, and sobas dead leaf green. Talens drawing for lines.
