Minder Property Marking Pens - Including 2 x Invisible UV Ink Covert Marker Pens and Warning Stickers

This is so disappointing, it clearly states its Invisible, so far I have marked three different mobile phones, black, gold and white - all of the markings are clear to the naked eye. I have also marked the TV with the same outcome. On one phone I was actually able to wipe off part of the markings even though it had been left to dry! It does glow when a UV light is shone on it but as I said there's no need as you can see it with the naked eye.I wanted this to invisibly mark items I sell to stop the returns from unscrupulous buyers who replace my item with their defective ones- thus reducing the need to deal with claims. Obviously as the pen is not invisible I can't use it for that purpose.I will be asking to return the item - whilst it was not expensive it is not fit for purpose in my opinion.

My daughter’s university accommodation was broken into before Christmas. A two month old laptop was taken. I bought it so that all residents of this house can mark their valuables with. I just wish there were more stickers for them

Do the job

Works well, have used this everywhere. Easy to find with UV light. Great value. Thank you

Just the item I was looking for quite pleased with it

Very good pens and used to mark things around the house would buy again thank you

Good product,but the picture should be of 2 pens and not 5 as I believe this is confusing.
