The Lyra 797 oil-based crayon is a durable marking crayon for clear and permanent marking on a variety of materials. It works excellently on, for example, metal, wood, rubber, plastic, stone, concrete, and other surfaces where regular pens can be difficult to use.
The oil-based composition provides strong and highly visible markings with good resistance to moisture, weather, and wear. The crayon can be used on dry, dirty, and slightly damp surfaces, making it especially popular in construction, industry, workshops, and civil engineering work.
Suitable for marking during cutting, assembly, measuring, and manufacturing where clear markings are needed under demanding working conditions. Available in several colors for easy identification and color coding.
