Ancient bog oak from Ukraine
5,400 years old (3,400 BC), this wood is of exceptional beauty and quality. The oaks that provided these squares rested at the bottom of rivers or at a depth of three to seven meters underground, deprived of oxygen.
The tannin, which remains in the wood, reacts with the iron salts, giving the oak unique physical properties: color, firmness and longevity. Each handle comes with a carbon dating certificate.
Carbon dating performed independently by Laval University located in Quebec. Each pencil is accompanied by a certificate of authenticity.
