Large-diameter wax crayons leave bold, permanent marks on surfaces standard crayons won't touch. Staonal Marking Crayons write on glass, metal, plastic, and fabric with strong pigmentation that stays visible through handling and exposure. The soft formulation excels at rubbings, pressing gently over textured surfaces captures fine details while delivering saturated color that makes subtle relief patterns stand out clearly. Artists working with brass rubbings or texture studies get professional results without specialized materials.

These extra-large crayons resist water and won't smudge once applied, making them reliable for outdoor marking, sculpture documentation, or any application where permanence matters. The substantial diameter feels comfortable during extended rubbing sessions and provides enough surface area for broad coverage when marking large objects or surfaces. Crayola offers these in boxes of eight crayons, available in two color options to suit different marking needs. The waterproof characteristic means rubbings survive handling and display without degradation, your captured textures remain as vivid as when you first pressed crayon to paper.
