Tip - Joker Mille, Hulk (CFL), Blu-V (UV)

This tip is made with the color hulk which changes colors under a CFL bulb (compact fluorescent light, they’re pretty common). The Joker is a Mille slice made by Dave Strobel, encased by me. Behind the joker is the color blu-v which appears clear but glows blue under a black light.
