Special collections - Hidden diamond.

Hidden diamond.

Mastery is hidden in detail. You can expect it from the collection that combines the know-how collected over four centuries, the finest materials and craftsmanship.

Just as the KOH-I-NOOR diamond, which is part of the British Crown Jewels, has become a standard of excellence and inspired the emergence of the KOH-I-NOOR HARDTMUTH brand, today we aim to show the world the selected jewels from our production through the Hidden Diamond product range.

A luxury Versatil leadholder from the Hidden Diamond line embodies a combination of the top-class Versatil mechanical components with carefully selected precious wood types and the surface finish achieved by applying special hardening oils and waxes. The lead having a diameter of 5.6 mm and the 4B hardness class offers an exceptional feeling when used for writing and sketching. A part of the leadholder is an integrated sharpener placed inside the push-button that is possible to screw/unscrew in order to use it. The leadholder is supplied placed in an elegant cigar-shaped case made of the same solid wood.

KOH-I-NOOR HARDTMUTH TIP: Your table will be beautifully decorated with a luxurious Retro Polycolor box, whose retro design is based on a successful collection made in the early 20th century.
