Molotow's Blackliner has a pigmented archival ink, that is not only resistant to water and chemicals, but is also fade resistant. The ink is also opaque, permanent, and quick-drying.
The Robust metal-encased tips guarantee fine and exact lines - perfectly suited for outlines. The "Cap-off" function protects the marker from drying out in 90-180 minutes, and the barrel has a slip-proof, matt surface for a sure grip.
