Worked Amazingly!
Needed it for an Army course and would have been lost without it.

Companion to the best map markers ever!
These are a must for minor corrections when using their pens!

Didn’t know what to expect and was pleasantly surprised
Purchased to go along with the staedtler color markers. Mostly writing on laminate and loksaks. Works well and allows you to easily wipe off any permanent marker. Curious as to how long it’ll last. Keep a small cloth to wipe nib clean after use.

Waste of money
What a waste of money this was. After receiving this I was excited to try it out, my excitement soon turned to disappointment. No matter what I did, the only thing that I could get to come out was clear liquid. It immediately went into the trash.
Save your money and just go buy the BIC correction pen.

Works well
It works well to erase Staedtler permanent marker from an acetate map covering.
