Add bold and fine lines to your planner with a single pen. This set of six dual-tip highlighters in vibrant colors is perfect for color-coding and decorating planners, journals, notebooks and study guides, with a broad chisel tip and an extra-fine bullet tip on each pen. Each tip features a plastic sleeve that helps maintain its shape, even when using metal rulers or stencils. The set also features fast-drying ink that won't smear pencil or ink lines beneath or bleed through most papers.
