A pack of 6 alcohol-based markers in a grescale colour scheme, as featured in the March Scrawlrbox. Used for one illustration only.
 
These markers feature a twin-tip design with Japanese nibs in 1mm fine point and a chunky chisel tip.  Smooth-flowing alcohol-based ink gives great coverage and layerability, in a good range of grey tones.
