Nice green color but it feathers to a moderate degree (hence the warning about using small nibs). It was bad enough that I thought my vision was blurring. 2 stars off. No bleed through. This is a "Polar ink" meant for clod weather and climates meaning it shouldn't freeze and damage your pen except in extreme conditions. I recommend this ink for it's stated purpose: cold weather IF a smaller nib is used. Otherwise? Might as well use crayons.
