About this Product


Unlock the magic of Gelly Roll UV, the first UV-visible gel ink pen. Our UV ink dries clear and can be seen only under UV light, where the ink glows beautifully in 3 luminous colors: Red, Blue, and Green. 

Explore your creative potential and turn every project into a radiant masterpiece. Gelly Roll UV is not just a pen — it’s a tool of transformation.

Every Gelly Roll UV pen set comes with a complementary UV keychain light. Simply press on to activate the light and watch your creations instantly shine. For extended use, click the “hold” button on top of the keychain light, and enjoy the UV effect for as long as you desire.

Overhead Lighting 

Gelly Roll UV ink behaves uniquely in various environments, such as natural light, lights off, and lights on. UV colors are most vibrant with no overhead lighting (in a dark room) but can be seen with any natural or indoor lighting under UV lamp.


UV Light

The compact and portable keychain UV light, provided with our Gelly Roll UV pens, is a great solution for smaller projects. 

For larger artworks, we recommend using a hands-free UV lamp. The increased lamp size and higher power benefit your craft by providing brighter and more even illumination. Moreover, the biggest advantage lies in the convenience of holding nothing else but your drawing tools. Nothing stands between you and your creation!


UV Light Distance from UV Ink

Achieve the best results by adjusting the UV light distance to your paper. Closer proximity (~4 inches above paper) may show more color vibrancy, while greater distances may create subtler glows. Experiment and the balance to suit your artistic vision.
