Invisible Ink Pen, Spy Pen with 3 PCS Mini UV LED Keychain Flashlight, Disappearing Ink Magic Pens with Black Light Markers for Secret Notes, Fit for Christmas Halloween Holiday Gifts (3 PCS)

Worked well for what I needed them for.

This is so cool! We used for a DIY escape room and it worked great! The kids loved it

Great little fun way to write messages. The colors do not "pop" out really they are all kind of the same. The blue did not look blue at all so I gave it 4 stars but you could see it under the black lights just did not really look blue. If you are looking for the specific colors these are not going to give you what you are looking for. If you are looking for pens to write messages that can only be seen under a black light they will do the trick.

These worked well for notes from Santa on Christmas morning. Kids love the magic of invisible ink.

Got it for my 6 year old as a gift and he loves it. It’s fun to use. It writes like your typical marker. It’s good quality and very durable. They seem to dry pretty quickly too.
