Unparalleled Value
An OLO™ marker is made up of two half markers, each containing approximately 2ml of ink. This means a double-ended OLO marker delivers around 4ml of ink—much more than traditional alcohol markers. And with OLO’s patented free-flow ink technology, over 90% of that ink is usable, compared to just 65-70% with other brands. No matter the comparison, OLO gives
Build Your Marker, Your Way
OLO’s design lets you fully customize your markers. With the OLO Connector Ring, combine any two colors and nib types to create the perfect marker for your exact needs.

Take it further with more customization options. Connect a matching OLO ink cartridge for quick, on-the-go refills, or connect the tapered OLO handle for better control and a painter-like feel. Available in black, red, or white, the connector rings and handles give you more ways to personalize your markers.
With OLO, how you customize is entirely up to you—the creative freedom is in your hands.

Patented Technology
Nearly all alcohol markers on the market rely on outdated technology that has remained unchanged for decades. These markers use felt material to hold ink, trapping up to 35% of the ink. This leads to faster ink depletion, inconsistent flow, and reduced overall ink capacity, causing artists to refill their markers more often.
We have completely revolutionized this approach with OLO’s patented free-flow ink system. There are no ink-absorbing materials to cause the issues other markers face. Our technology ensures smooth, consistent ink flow from start to finish, with over 90% of the ink utilized effectively. This means you get more usable ink and a superior coloring experience.

A Color System That Works
OLO’s color system is meticulously structured to simplify your artistic process. Each color is categorized by a Letter, which identifies the color family; a Hue, representing variations within the family; and a Value, indicating the color’s intensity from light to dark. This system helps you select the perfect shade and organize blending groups for seamless transitions and harmonious blends.
Replaceable Ink
Refilling traditional markers often proves to be challenging. Decades of research show that many users prefer to discard empty markers rather than deal with the messy and time-consuming refilling process. Common issues also include uncertainty about the amount of refill ink needed, difficulty locating refill products and tools, the need to travel with refill inks (and the amount of extra space they take up!), and the general hassle of the refilling procedure.
OLO’s Replacement Ink Cartridge system simplifies the process. Remove the seal from the Replacement Ink Cartridge, reuse or replace the nib, and use the cap from your empty marker.
Enjoy a quick, clean, efficient refilling experience that gets you back to creating in seconds.
OLO ZERO
Calling 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, add texture, or minimize and correct mistakes.
