The PILOT PERMANENT MARKER 100 uses a new development in permanent oil-based ink technology, Controlled Surface Properties (CSP) Ink. CSP ink delivers class-leading performance in terms of vivid ink colour with a high fixing strength and abrasion resistance for all types of surface including plastic, metal, wood, card and glass. The PILOT PERMANENT MARKER 100 also delivers one of the longest cap-off times (24 hours) which mean that this marker pen will continue to work perfectly, long after when other types of permanent marker may have dried up. Available in 4 CSP ink colours - Black, Blue, Red and Green. 4.5mm Bullet tip gives a 1.0mm line.
