## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    This is a useful tool, especially if you want to leave others in your family a confidential message
  

*by W***E on Reviewed in the United States on August 17, 2013*

I mostly regarded these markers as for child play, but after getting them I realized that a message can be displayed in plain site, such as when you will return home, that you don't want visitors or potential burglars to see.  It must certainly be uncommon for UV lights to be a tool in average home burglaries.  Only those you tell about your system and who have access to a UV light are likely to read such messages.  Don't though put both the flashlight in plain site, so the few smart burglars get ideas of your intent.

    Excellent"
  

*by C***. on Reviewed in the United States on January 2, 2013*

Got these for Christmas for our 7 year old daughter. She had great fun writing secret messages and then using the led light to make the invisible message appear. College kids got a hoot out of "body art" using these pens. We all had "invisible" mustaches that became visible only when black light shone on them. Hearts on hands, etc. this was a really fun gift for many ages.

### ⭐⭐⭐ 







  
  
    I would probably pass for the price if I saw it in a store
  

*by T***Y on Reviewed in the United States on January 11, 2014*

I would probably pass for the price if I saw it in a store.  I think it might be worth a buck or 2.  The 3 markers are very Very small.  The 3 together are about the same size as a pencil.  All of mine work.  The blue shows up as a whitish color under a blacklight.  This will be fun for decorating, just disappointed that they are so small.
