OLO offers an innovative, customizable alcohol marker designed with your creative needs in mind!

With its patented cartridge free-flow ink system, OLO ensures consistent, controlled ink flow throughout the cartridge's life, providing more usable ink than other alcohol-based markers. Each half-marker contains 2ml of ink, surpassing standard markers. Pair any two with an OLO connector ring to create a dual-ended marker with over 4ml of ink.

Customize your markers by mixing and matching colors to suit your artistic preferences. Plus, get a complimentary connector ring added to your cart automatically when you select any two half-markers.
