are the blank sides usable with dry or wet erase markers and pens?
I just checked, and the dry erase works well (though I wouldn't recommend writing over pencil marks, as the dry erase ink settles in the indentation, and I wouldn't leave it on over an extended period of time in case the dry erase stains). Pencilling lightly on the cards works well, and as weird as this sounds, I couldn't find a wet erase marker here at work to test it out. Since the edges of the card aren't sealed, I would be hesitant about using a wet erase marker on the cards.
