Pros: Bright colourful blister packaging. Great fun stocking filler for younger child. Cheap to buy. Possible Security use? It actually works as intended, not all things do!

Cons: All wording is in Chinese, not english. Looks cheaply made, but then it is cheap, and I can see this when ordering.

Other: Great for the price! recommended as a stocking filler item without spending a lot of money.

Pros: Writes with invisible ink that only reveals in UV-Light The tip is sturdy, it doesnt break while writing on harder materials such as stone and bricks. Dries up fast. Strong concentrated beam from the UV-lamp.

Cons: Transparent lids. (it should be protected from sunlight) Perhaps a little short reach of the beam from the Lamp for revealing messages in a dark room.. The ink leaves marks in some materials that reveals in normal light.

Other: Perfect usage for creating Geocaching Mysteries.

Pros: Good cheap markers with best price. Excellent quality of all materials. Inks looks clearly with the light of the large ultraviolet light. Batteries included) Small marker as good as the big. I like the both)

Cons: Weak flashlight, lettering is not convenient to read with it, but to write is comfortably. The paint can be erased in the first 30 seconds after writing.

Other: Markers have high quality, I advise.
