Bought these to put in my prize box at school as well as sell in our school store. My students love these- one of our best sellers- kids love these - has a pull out white piece which you remove to get the uv light to work- kids write a message with the pen (which you can’t see) until you shine the light on the paper or body to see it. Works well- great overall price point as you get a lot of pens, very simple to use as well. Like how the main pen has lots of different bright outside colors and not all the same. My students have so much fun writing secret messages. Def will buy again.

I taught a lesson on spies during the Revolutionary War. The students used these invisible ink pens to write secret war messages to each other. It was a great way to get them involved.

Students loved the mystery ink pens to celebrate the end of STEM club. They worked well. Students talked about them for several days after getting them. Great price for a fun writing utensil.

Regalate alla mia bimba di poco più di 2 anni, che adora disegnare, è stata molto contenta di queste penne molto particolari. Ci ha messo un po’ a capire il funzionamento!Adatte sicuramente a bimbi un pelino più grandi, ma tutto sommato è un buon prodotto diverso dallo standard!

Der Versand erfolgte problemlos, es gab eine schnelle Lieferung. Was ggf. deutlicher hervor gestellt werden sollte, ist, dass die Farbe der Stifte keine Rolle spielt, da unter dem UV-Licht alles die gleiche Farbe hat. Aber daran habe ich als Kunde vorher nicht gedacht.

Perfette, fanno quello che c'è descritto. I colori sono solo dei pennarelli esterni e non dell'inchiostro, che è uguale per tutti.Spedizione impeccabile. Buon prodotto

J'ai utilisé ces stylos dans le cadre d'une formation pédagogique et c'est vrai que c'est incroyable. Vous écrivez avec le feutre et rien ne se voit, même par transparence. Il suffit de placer la petite lampe pour voir apparaître le message. Bien pour communiquer avec quelqu'un comme un espion ! Les enfants adorent.

Reçu rapidement et dans les temps, le cadeau d'une grande simplicité à fait forte impression. Simple comme bonjour, chaque stylo possède sa propre lumière UV pour vérifier son message.A acheter sans hésitation!Merci.
