Perm Marker Bullet tip WT PK12

Over 30 years old, X100W is the biggest seller of its type and used in industry to mark non-absorbent surfaces such as metal, glass, plastic and rubber. X100W White Marker has a thick bullet tip and gives a line width of approx 3.3mm. Because of the china clay pigment it has a valve to control the flow of ink which passes down and around the tip, rather than through it.
