SL-1 Superline Marker with Round Tip
Refillable - Easy to use
Universal Superline Markers are precision machined, valve action, refillable markers. These markers are manufactured from high grade aluminum alloys and feature a precision valve with an O-ring seal which feeds ink when the tip is depressed. A threaded cap on the barrel is removed for filling. Replaceable felt tips are available in a variety of styles which make this pen a perfect choice for artistic marking. Recommended for use with Type FD inks for both porous and non-porous surfaces.
