A water-based, twist-up pen-type mechanism containing weathering material designed to easily add realistic, three-dimensional dirt and desert effects to scale models. 
The pigment behaves similarly to a waxy marker, featuring a bright yellow-sand hue styled after African desert terrain.
Direct Application: Apply directly from the pen onto high-wear surfaces like tank treads, lower hulls, and rally car chassis to leave thick, textured dirt patterns.
Wet Blending: Spread the wet pigment smoothly across surfaces using a wet paintbrush, a makeup sponge, or your finger before it completely dries.
Correction & Clean Up: Wipe away mistakes or excess material cleanly using a simple damp cloth.
Finishing: Let the formula cure entirely to a durable coat, then spray a flat clear topcoat to lock the effect permanently onto the plastic.
