Elegant box + replacement pen tip (1 piece) + pen bag (more convenient to carry)
The solid-state pen also ensures that there are no ink stains, balls or cold ink, the hand is not stained when writing a line break, and the front text is not consumed. The tip of the pen is made of special alloy steel. The writing principle is that the friction between the tip and the paper creates a solid oxidation color on the paper. This does not fade even after 25 years of writing. This ink-free pen extension won the Outstanding Design Award 2008, and the architectural design of the Chicago Athenaeum Museum is considered the world's most prestigious design award - the "Good Design Award"!
