Precautions
The ink is slightly visible in the sun. Under bright direct sunlight, the ultraviolet ink from the moonlight pen is almost invisible, but under normal artificial light or candle light, it is completely invisible.
Easy to write with two. We recommend buying at least two pens, as this will make writing and drawing easier. Since the ink is completely invisible, it may be difficult to figure out what has been written, so use the light of the second pen when drawing with the first pen.
The pen contains 3 LR41 batteries.
Package includes:
3cp luminous pen set (a set includes 1pc pen and 3pc electronics)
