Waste of money

The tip is so sharp it scrapes your message into the paper no matter how light you try and write

The media could not be loaded. How this works is you write something that looks hidden to everyone, to display what you wrote use the UV light and shine it. I initially thought that it would be ink at first, and some 24 hours or so later it would become invisible and only visaible once the UV light shines on it. In this case this is instant invisible ink, which is a let down, but the idea still works the same. Just think it would be more of a real spy stuff if the ink disappears.Think that if giving this to a kid, if they are too young they may press the uv light and shine it in the eyes, that is detrimental, so suggest 12+ use this or parental guidance etc.. You can replace the batteries, this product takes 3 batteries, and if you find refils, you can also replace the ink. The pens are all light and you get 5 of them in the pack.In my opinion this is a near perfect product, to make this better I would make the pens heavier as they are very light right now, and I would use real ink which disappears on paper after 24 hours, those are the real invisible type of ink.There is no fun in it, if starting out invisible. If that cannot be done, then how about a UV light on both sides, one lighting the road on paper so you can see what your writing at the same time? Then I would rate 5.

This product comes inside of a plastic packaging, inside the packaging you'll find 5 pens, these pens have an in built UV light attached at the top of it, where a lid would usually go.The pens are of decent quality, it's not the best but it isn't bad. Easy to use.
