This Mr. Pen set features gel highlighters in a range of earthy colors. Unlike traditional markers, these are pigmented wax sticks that use a twist-advance mechanism. Because they do not use liquid ink, they eliminate the risk of capillary "bleed-through," making them suitable for the ultra-thin paper found in many religious texts or legal documents.
The wax-based formula is atmospherically stable, meaning the markers won't dry out quickly even if a cap is left off for a while. The earthy palette is designed for high legibility without the brightness of neon. To keep the markers in good shape, they should be stored away from high-temperature areas, as the wax core can deform if it gets too warm.
Since these act more like a crayon, they can leave a tactile texture on the page. It is often helpful to highlight first and write second, as the wax surface can sometimes make it difficult for other pens to write over it. The tips will naturally round with use, which provides a smooth glide but less precision than a sharp chisel-tip marker.
For those who need a more precise edge for technical work, the Alvin 5.3mm Chisel Tip highlighters offer drafting-grade accuracy.
Specialized wax highlighters are a great addition to any home office, and you can see more varieties in the highlighter marker assortments category.
