The smooth 0.7 mm O-refill ensures consistent writing with a length of up to 2000 feet, while the durable alloy-enhanced pencil tip, measuring 5.1 millimeters, only wears down by 1.46 millimeters after 600 meters of use. Featuring a reverse S-shaped bolt-action mechanism, it allows effortless switching between pen and pencil, adding a fun fidgeting element. The all-metal construction, with a compact 4.13-inch aluminum body and skeletonized barrel, is paired with a strong stainless steel clip, combining durability and functionality in one sleek design.
