The solid core format makes them durable for scoring and marking on rough textures, and they fit into Markal no. 101 and no. 102 holders for safer, controlled use. Marks remain readable in temperatures from -50°F to 150°F (-46°C to 66°C) and can be applied on metal, wood, glass, plastic, concrete, rubber, cardboard, and paper.\u003c\/p\u003e\n\n\u003ch3\u003eHow reliable are these sticks on rough or greasy surfaces?\u003c\/h3\u003e\n\u003cp\u003eThe Paintstik formulation is designed to adhere to uneven and contaminated surfaces where liquid inks often fail.
