Juma Black pen blanks are a high grade, modern raw material for the manufacture of components and works of art such as artisan hand made pens. JUMA consists of a mixture of different mineral base materials compounded with a resin component.

The essential characteristics of Juma Black Pen Blanks are:

  • excellent mechanical machinability i.e. for drilling, milling, grinding and polishing,
  • minimum breakage risk due to high coefficient of elasticity and high elongation,
  • high-quality surface due to high surface hardness and minimal abrasion losses,
  • resistant to all conventional substances such as cleaning agents, oils, greases, weak / medium acids and bases,
  • very low water absorption (hydrolysis resistant). – possibility of thermal moulding in boiling water,
  • can be polished or lacquer coated to manufacture polished or matt surfaces,
  • pleasant to the touch due to good thermal properties.

We recommend a final finish / polish using buffing wheels and rubbing compound such as Mirka Polarshine 35 (MP35K) followed by rubbing compound e.g. Mirka Polarshine 10 (MPT10K) For extra shiny end finish use Mirka Polarshine Liquid nano Wax (MPWG1)
