This Bic 2300 Permanent Marker features an ultra-resistant chisel tip that will not bend or retract, even under pressure. The alcohol based, low odour ink is both water and light resistant for long lasting use. The chisel tip writes a 3.1-5.3mm line width on most surfaces for both bold and finer lines. The marker also has an extended cap off time of up to 3 weeks without drying out. This pack contains 12 black markers.
