Kokuyo's clear crayons from Japan bring a quietly remarkable quality to children's art: transparent, oil-based pigments that layer beautifully over line drawings, building depth and luminosity without obscuring the work beneath. This 5-piece set has a second surprise- under UV light, the colors glow, turning finished artwork into something altogether different after dark. Smooth and soft to the touch, they suit a wide range of ages and skill levels, and pair naturally with coloring books, sketchbooks, and printmaking projects.
