Description
Here’s something really fun: three Gelly Roll pens loaded with invisible ink! The classic Gelly Roll body has been filled with special UV-sensitive ink in three different colors: blue, green, and red. A smooth-writing 1.0 mm tip makes it easy to apply the ink to paper—but it’s not so easy to see it!
In our first photo, which shows the three pens and UV keychain light (included with each set), we’ve already written on the page with Gelly Roll UV. It only looks blank—but when you shine the mini blacklight on the ink, the colorful writing is revealed.
In addition to writing secret messages, these pens are a great way to create artwork that changes color or reveals hidden details under blacklight.
Made in Japan.
