OLO RK Red Black

OLO markers offer a unique customisability- some brands offer only one type of nib, and others provide a chisel and brush style nib in each pen. With OLO, however, you get to choose what is right for your purposes, on a colour-to-colour basis. Whats more, OLO does not allow this customisability to come at the expense of ink quantity, introducing their own patented technology to allow full usage of up to 90% of ink, compared to the industry standard of 65%.
