Pentel Super Hi Polymer Mechanical Pencil Leads (12 pk)
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.
At Flax we carry these in .5, .7 and .9mm
