It usually takes three to four markers to blend a sequence of colours, but constantly sorting and categorising markers can interrupt the creative process. M-MARKER provides a solution. With a magnetic marker packaging and a quadrant-shaped body, users can easily combine four markers. Not only is this convenient for colour classification and grouping, but the design also makes it easy to keep groups of markers together for the next use. In addition, the markers' ergonomic form makes it more comfortable to grip.
