Work just fine
1 of 1 found this helpful This thing is cheap BUT it actually does 445-450nm blue at a 'safe' power. Works great on glow in the dark stuff and eat battery like crazy but I feel 'safer' letting my daughter handle this one (with lots of supervision) without fear of her cutting through walls or burning herself.. I don't think this is a class 3a (probably stronger then that) but still not hot on skin.
