Things to note
Ink is slightly visible in sunlight. The UV ink from Pen is very slightly visible in bright direct sunlight . but under normal artificial light or candlelight . it is completely invisible.
Easier to write with two. We recommend buying at least two pens as it makes writing and drawing a lot easier. Because the ink is completely invisible it can be difficult to figure out what has already been written . so use the light from a second pen as you draw with the first.
The pen includes 3 LR41 batteries.
