When tested on the back of my TV & other goods found it wasn’t invisible & can still be seen now.
The light is not big enough or bright enough to do much so I am a little disappointed but like said it’s cheap & maybe ok for children.
I just tested it on a plain piece of white paper this had a better result & with the light shinning was ok so it must be the black surfaces of my TV etc.
Don’t expect too much & if needed for security purposes I would spend a little bit more on a better product.

I ordered these for my two daughters to keep them occupied in the school holidays and on weekends, as they are into spy-style toys and have previously owned invisible ink pens in the past. However, the delivery took just under a month so it was challenging to find them an activity in the meantime and I am assuming that these were probably then shipped from the far east. When they finally did arrived, they were exactly what I expected, two purple invisible ink pens that had clear instructions and labels. You simple write with the pen in a normal way although you can't see the ink, and then you press the little button on the pen lid to activate the small blue light which reveals the writing. My daughters have enjoyed using these a lot, writting on walls and sending secret messages. My only issue was the delivery which did take a rather long time for these products to arrive.

Got them to keep the kids amused and they work ok ,long shipping time but i expected that.had to put one of the lights back together,not the easiest of things, after my inquisitive 8 year old undone it (yes he likes to test me like that) so wouldn't recommend it for young children unsupervised as there are small parts in it. I'd get them again no problem but haven't used them on anything more than paper (and skin,invisible tattoos are fun apparently but as you can't see them without the light ,why not?)

I was a little disappointed when they arrived because I had brought it for me and for my friend and as we are both girls I was confused when a green and blue one came? I may have missed it in the description but I am sure I didn't, it was not clear that that was not the colour. Also the design was a bit odd it says 'lnyvisbie pens'. Even though I should have looked a bit closer at the picture it was very hard to see the design. Other than that, it works, the light does go off every so often and you have to turn it back on. It's readable. And fun. So that is why I give it 3 stars.

So to make these pens better please take clearer pictures and state clearer that the colour might change. Oh and try to stop the flashy of the light! Good though, it will do!

This item was despatched extremely quickly & arrived much earlier than expected. I bought them for my granddaughter's 8th birthday. She thought it was a great product - Ideal for those 'secret' entries she wants to put in her new diary!

I ordered this for my 7yr old daughter as she desperately wanted a secret diary and they were sold out everywhere, so thought this would pacify her for the time being! She thought that it was great! She loved writing messages that no one else could see unless she shone the torch. It is rather delicate though, as a couple of times, she has pressed too hard with the nib, which forced the torch out of place. It was easily corrected by realighing it. Still, good value for money!

Pens arrived quickly, both worked at first, one stopped working after a few times my stepdaughter used it. Ive now ordered a replacement off Amazon for her, hopefully this one wont stop working!

It is as described and allows you to read invisible notes you may have made in the past even with a different diary pen. However, the ink does run out fast if you use it constantly and fast.
