Ginger Well, maybe, I have only white boards and paper around, and together with other colors, which are invisible on a dark surface, it still does not make much sense for me. But I am glad, white markers are not unwanted everywhere ;)
Krzysztof Maciejewski Just my imagination:-) Actually I've never seen a ream of black paper. I wonder now, maybe this white marker serves as a correction fluid ???
Ginger I tried this last option, but no, it does not remove other colors .Such a puzzle ;)
Krzysztof Maciejewski Exactly, a puzzle. I imagine now a man, who came up with this idea - we will produce a WHITE marker :-D
Ginger My students had a twisted idea, that it is for blind ppl... Yeah i know, it sounds bad ...
Krzysztof Maciejewski :-D Colour-blind perhaps ;-)
Krzysztof Maciejewski Very useful, when you have to mark red inscriptions on a black background. It's a very common case :-D
