These are the pens of choice for marking on transparent map overlays and laminated maps.

I've used these pens for many years while in planning and operational roles on search and rescue missions.

Choose between permanent or non-permanent ink. The non-permanent ink can be wiped off using a damp cloth, but your markings may not survive a rain storm. The permanent ink will easily survive getting wet, but minor erasures can be made with a plastic eraser, and the sheet can be wiped clean with a cloth dampened with alcohol.
