good for bad students :p – Invisible Ink Pen with Ink Revealing Blue LED (3*AG3) Reviews

Involvement:General (knows how to use it) - Ownership:1 week to 1 month

-Comes with 6 batteries (3 already inside, it comes working, and 3 extra) -Looks like a normal pen -UV Light isn't that strong, so it might be imperceptible during tests, but I wouldn't advise anyone to cheat (I never did).
-The ballpoint doesn't fully retract, which makes me think the ink might dry out eventualy with no use
-They could have made the uv light a little weaker, and maybe even somehow focusable so it won't spread out and people notice a shinyng pen.
Overall a good think for its price.
