Official Product Details:

Levenger Bottled Ink is what fountain pen ink should be: smooth and rich, designed to last, formulated to delight. Levenger inks resist fading as well as feathering, which is why you’ll have such a satisfying writing experience. They are moist on your nib but dry readily on your paper (especially helpful for left-handed writers). They're lightfast and maintain a crisp line without spreading. The even saturation ensures no skipping. And Levenger inks come in a panoply of rich colors—to match your mood, suit the occasion, enliven the page.

Made in the USA.
