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.

Set no. 1 includes .05, .1, .2, and .4 mm nib sizres. Set no. 2 includes .3, .5, .7, and 1 mm nib sizes.
