  This ink is not for fountain..., July 11, 2011
By anthonyjong - See all my reviews
This ink is not for fountain pens and it required an extreme heat (ie: stove or hot halogen light) to make this invisible ink to be visible. I thought the ink will be visible from the heat of my finger such as the one in some check book, but it doesn't. I have to put the paper directly under my halogen table light for 7-10 seconds to change this ink into a blue shade. Not worth the money.
