1 Pc Invisible Ink Gel Pens Multifunction Security Marker LED UV Light Magic Marker Ballpoint Creative Secret Pen School Office Supplies

I mean it does what it says on the tin: invisible ink. The uv light on the top is helpful though not very strong. Only annoying thing was the sticker which was impossible to peel off cleanly and has left the pen permanently sticking and ugly. Still, that’s only a minor annoyance and otherwise it’s a decent pen.

Bought this for our daughter to have fun using and after just 2 days the light stopped working. A bit of a disappointment!

I wasn’t expecting much from this but at least it should have been working when I got it only was for a bit of a fun gift but the pen works ink is completely invisible until you shine a uv light on it but the light on the pen was completely useless and extremely poor quality

Was broke

the LED fades out too fast and the light is too wide. A narrower focus would be better

It was ok but not worth it.There was a sticker which when peeled left lots of paper left wich was tacky.

Huge sticker that wouldn’t come off and left indentations in the page which defeats the purpose entirely.

Hält nicht mehr und nicht weniger als in der Beschreibung steht.

Usata su carta e cartone scrittura scorrevole e sotto illuminazione si vede bene

Inutilisable.L'encre n'est quasiment pas visible même avec la lampe UV.On voit davantage la marque de la mine sur la feuille.Cerise sur le gâteau, cet article ne peut pas être retourné.

Copiar en un exámen nunca fue tan fácil 😜
