OLO Alcohol Brush Markers

Each OLO half-marker contains 2ml of ink, for a total of 4ml in an OLO double-ended marker. Traditional markers only have approximately 2ml of ink total. OLO’s patented free-flow ink technology utilizes over 90% of the ink compared to standard marker technology, with only 65-70% ink usage. OLO’s unique design features let artists custom-build marker and marker sets. For example, the OLO Connector ring combines various OLO™ marker ink colors, nibs, and more. Experience a new way to color with OLO accessories such as the Brush Handle. 

Manufactured in Japan, the new OLO™ marker is developed using patented technology that features a free-flow ink system. Traditional art marker manufacturers use a technology that has remained unchanged for over 30 years. Unfortunately, there are significant issues with this outdated technology.

Traditional markers contain an absorbent material in the barrel that holds the ink in place. However, this same material traps as much as 35% of the ink, causing a volatile ink flow that degrades as you use the marker. The result limits the overall ink capacity that the marker can hold. OLO’s patented technology solves these traditional marker issues. Thanks to the free-flow ink system, OLO markers hold twice as much ink as any other alcohol marker, with over 90% consistent ink usage. 

Due to the outdated technology of your standard alcohol marker, refilling the ink is typically messy and time-consuming. In addition, this same technology degrades over time, causing you to refill your marker more as the ink capacity lowers. With OLO, there is no absorbent material to degrade; simply replace the ink cartridge.

Simply purchase a new ink cartridge when your OLO™ marker runs out of ink. Then, remove the nib and cap from your empty marker cartridge and use it with your new Replacement ink Cartridge. Then, you are back to creating with a few simple steps—no ink to meticulously drip, no accidental overfilling, no ink blobs, and no mess. 

**Calling a colorless blender a “blender” is misleading as 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 to dilute color, add texture or minimize mistakes.
