Elemental Ink Pens
Pack options* Due to high demand, expedited shipping is not available for the 9 Pack Multicolor.
What paper does it work on?
It works on all types of paper!
Isn't it going to light the paper on fire?!
No! The Elemental Ink disappears at 104°F (40°C) whereas normal paper lights at 451°F (233°C).
How cold does it need to get?
Freezer cold works well but dry ice or other arrangements work too if you want to take it to the next level!
How it works
Disappears With Heat
Becomes completely invisible when subjected to heat. Direct flame works well but also a hot lightbulb, a hot mug of just boiled water or even an iron work too. Around 104f (40c) is the temperature that the ink starts to disappear.
Reappears With Ice
Once disappeared, the ink is completely invisible until it's chilled to freezing temperatures. Thirty seconds in the freezer works great!
This is one of my favourite trick tools to use. Your friends will be amazed too when they see the ink vanishing in front of them leaving just your secret message, or whatever you want to reveal.
The pens themselves were difficult to write with, but did work as they said for the disappearance and reappearance. Also, the shipping took forever.
Sorry your pens took longer to arrive than you hoped. We offer shipping as fast as 1 business day but I see you selected our economy shipping option which is 10-15 business days. It's easy to miss the options at checkout but the faster shipping options are more expensive so we don't have them as default :)
Sounds like you're having problems with the pens writing too? From your feedback I'm unsure exactly what the issue is but we're happy to help out and replace any defective pens if you want to drop us a message!
Very cool product. Would have given 5-star but ink on one pen ran out quicker then expected so would advice buying multiple ones.
Hi Ogo! Sorry you got a bad pen! If you want to drop us a message then we'll be happy to sort out a replacement for you with some extras for the inconvenience :)
Like many other commenters I am disappointed with the scratchy, scrapy performance of the pen- a felt marker would be so very much better. Also, since I am demonstrating these pens to chemistry students it would be lovely if you shared the science of the thermochromic substance you are using. If you haven't patented this , please do so tha you can share the proprietary secret and then we can teach with these.
Thank you so much for your feedback! So sorry you're not totally satisfied with the quality of your pens. Drop us a message and we will try to help We are also thinking about releasing marker elemental ink pens so watch this space!
Without going into too much details behind the science of it all - the ink contains microcapsules which hold the colour and react to changes in temperature
Was super excited to use these pens for my D&D campaign. I had high hopes, but was very disappointed. These pens barely show ink on paper. The black ones write super faded. You can’t blend the ink with regular black ink whatsoever
So sorry your pens don't work as they should!
We will send you a replacement pack ASAP!
This is a cool item. I’ve gotta figure out how to make a better covering up design but that’s on me.
