OLO ZERO, A.K.A. "the blender." Calling what is known as a "colorless blender" a “blender” is misleading since it does not allow for traditional blending techniques. The importance of this marker is in the absence of color, hence the name ZERO. Use ZERO with OLO alcohol markers to dilute color, create texture and pattern with color, assist with controlling and blending colors, minimize mistakes, and so much more. A marker artist's must-have tool! Half-markers: One OLO half-marker has 2ml of ink, plus over 90% more usable ink than other alcohol markers. Use an OLO Connector Ring to combine any two half-markers for a double-ended marker with 4ml of ink. Combine half-markers to create unique double-ended markers that feature your choice of colors and nibs.
