We are pleased to introduce new K-55 markers! The K-55 is our most popular acrylic paint marker, we've had many requests to expand the line. The K-55 is now available in black, silver and red, classic colors and favorites among Krink users. These new colors compliment the original five fluorescent colors, which glow under a black light. All colors are vibrant and opaque, ideal for working on smooth surfaces, such as paper, glass and canvas.
