Finally found the perfect 5 round liners I used to hand make back in the 80's-90's, just perfect between thin and thick, I love these!
Love them, the long tip is great for seeing what you're doing, they hold enough ink to pull pretty long lines too. Pretty quiet, and smooth awhile running as well.
Muy buena calidad
the stability of these cartridges is amazing, I will definitely always use this brand
