This is a pencil with a replaceable and mechanically extendable core.
This elegant mechanical pencil from Uni is crafted from pure oak wood, over 100 years old and previously used in whisky barrels! The smooth and warm texture of the natural wood gives this pencil a classy appearance and a weight in the hand that's hard to beat. This version is the "click" style, and features an eraser on the end as well, in a lovely natural wood color. It's about 13.7cm long, 1.2cm wide, and comes with 0.5mm lead.
