Colored leads noted for their strength, resilience and density. Created with a special composition that results in a very strong and flexible lead. Twelve leads per tube.
One of the strongest and highest quality series of leads on the market. Formulated under an exclusive process to improve strength yet retain blackness and smoothness. These leads require only light pressure to create dark, clean lines. Super Hi-Polymer formula reduces the risk of lead breakage and consequently saves lead. Packaged in plastic tubes. Twelve leads per tube except where noted.
The composition of Hi-Polymer lead is synthetic resin, graphite and carbon, offering remarkable strength and flexibility. Each tube contains a dozen HB leads.
