Mitsubishi Hi-Uni is one of the world's finest pencil ranges, vying with the top model ranges from Faber-Castell, Staedtler and Tombow for accolades from the pencil cognoscenti.
The Hi-Uni was introduced in 1966 and achieves greatness through exacting standard of lead production. The graphite and clay components of the lead are both uniformly fine, so that the line quality is high, and uniformly mixed, so that breakages are minimised.
Hi-Uni is painted in a traditional Japanese maroon, likened to a wine red, with black and gold accents. The hexagonal barrel changes to cylindrical above the gold ring, in a neat design touch.
In 12's these pencils are supplied in a protective hard plastic flip-top case, that keeps individual pencil in its place so they do not rub together more than necessary. We will supply a case for every 12 pencils you buy in one order.
- [About pencil hardness grades] : A greater percentage of clay results in a harder pencil lead, and lead is graded by hardness. Pencils graded H, F, HB and B are of average hardness. Pencils ranging from 2B to 10B are softer and are used for sketching, while 2H to 10H pencils are harder than average. A common American #2 pencil is equivalent to an HB pencil.
- [These are the lead grades from hardest to softest] : 10H | 9H | 8H | 7H | 6H | 5H | 4H | 3H | 2H | H | F | HB | B | 2B | 3B | 4B | 5B | 6B | 7B | 8B | 9B | 10B.
