Discover a new way to colour with OLO Marker Sets, designed to give artists complete flexibility and outstanding performance. Featuring vibrant alcohol-based inks and smooth blending capabilities, these innovative markers are ideal for illustration, comics, design, and mixed media projects.

OLO’s unique modular system allows artists to customise their markers using the patented OLO Connector Ring, combining colours and nib styles to create personalised double-ended markers. Marker bodies are colour-coded for easy identification, with black barrels for brush nibs, dark grey for chisel nibs, and white for the ZERO colourless blender.

Each OLO double-ended marker contains 4ml of ink—approximately twice the capacity of many traditional alcohol markers. Combined with OLO’s patented free-flow ink technology, which utilises over 90% of the available ink, these markers deliver exceptional longevity and value.

Whether you're starting your collection or expanding your palette, OLO Marker Sets provide a versatile and innovative colouring experience for artists of all levels.
