Akua Intaglio Water-Based Ink, 8-Ounce Jar, Phthalo Blue

These inks have no smell and provide a brilliant and bold color. On the downside, they don't dry. This means that clean up is a nightmare of transferring inks from surface to surface. Several months after you use them spots will remain wet on both the paper and any surface you happen to touch--regardless of how many baby wipes you use to try and keep things neat.
