I just this week used the Bohn marking pencil (the pink refill). I machine washed as soon as I was done and it all came out. I just let it air dry and when I get home I hope it is still all gone. I have had this since April and this was the first opportunity I needed it for. I was marking a white embroidered top my SIL had done. So far I am pleased with it. Nice fine line for use with a stencil.
