beware of this pen....a rather detailed test was made by one of the well known and respected teachers and she has reservations and gives caution about how they are used. I believe the subject has been discussed just recently

I couldnt find them so got papermate erasable ones. Brought home wrote on white fabric. Washed with dish soap. Disappeared. Put in freezer. Next day looked u could barely see. Haven't tried ironing forgot about it. Will try and let u know

Ive been using these pens for about a year and love love love them!

I've never had a problem with them. Love em! A blow dryer will erase the marks as well. So will the dryer.

Good idea on the blow dryer ... sometimes you just don't want to press!!

Have had mine 2 weeks, have only done test swatches so far.......
