Sakura Pen-Touch 2.0mm Paint Marker

Sakura's liquid paint marker option for semi-permanent sighter.  These markers are bit easier to remove than the solid paint markers from Sakura but they stay on better than Skafar's Wax especially in warm temperatures. You can remove Sakura markers with hand sanitizer. I keep a small travel bottle of sanitizer in my chest pack. I add a few drops to my fingers and then roll the leader between my fingers with the sanitizer. The marker eventually dissolves and wipes clean off the leader.
