Designed and engineered to last a lifetime, this mechanical pencil is the best one you'll ever own or use. The custom-made writing device is machined from one solid piece of metal to give it incredible strength and tested for weight balance from end to end before being assigned a unique serial number. Every pencil contains multiple, intricate parts — each of which is made of metal except for the eraser and o-ring — but appears to be a single piece thanks to the seamless hand-blended design. A hidden screw system holds the pencil together and can be disassembled using the provided Allen key. The pencil arrives with a 0.5mm mechanism, five erasers, a cleanout rod for removing blockages, and a removable powder-coated clip. Available in stainless steel, titanium, and bronze.
