Permanent Map markers
These are PERMANENT markers which is not what the description says. Only buy these if you are looking for PERMANENT markers. Luckily, I have a practice map and did not destroy my actual flight map.
Fantastic field use
Best pens on the market. Even when you write on the vinyl, when you want to remove the excess just use hand sanitizer it will come right off. used repeatedly in the field and in conflict.
Lumocolor Pens Used on Vinyl Map Case
Do not use the pens on the vinyl of a map case!!!I just back from AT and I had used the Lumocolor Perm. Pens on my vinyl map case, as instructed from both the clerk at the PX and an Infantry Captain. At the end of 12 days, the ink would not come off of the vinyl!
