Pica Classic Blackboard Chalk, 0.5" (13 mm) square, 12 pieces

Family-led since 2005 and based in Kirchehrenbach, in the Upper Franconia region of Germany, Pica is the originator of the Deep Hole Marker, a marker designed to write on hard-to-reach spaces and on almost any dry surface. Since then, Pica has continued to expand its offerings, introducing a multitude of markers and pencils for writing on nearly any surface under almost any condition: wet, dry, hot, or cold. Acting on advice from tradespersons of all types, Pica continues to expand its range from construction to carpentry, tiling to welding. Moreover, a company-wide commitment to sustainability means that their products are not only built to last, but that refills for a wide variety of tasks are available for most styles.
