Klein Tools Skribes™ Fine Tip Black Permanent Markers are designed for tough jobsite conditions. With durable tips, they create vibrant, long-lasting lines for detailed marking and labeling. The professional-grade ink writes effortlessly on wet, dry, oily, and abrasive surfaces, resisting clogging for smooth marking. The marker's 72-Hour extended cap-off life prevents it from drying out quickly. The anti-roll triangular shape and built-in hard hat clip keep it easily accessible on the job.
