This is the 2021 limited edition red Kaweco Special. Since you are looking at this pen, I assume you have considerable knowledge, so I don't think it's necessary, but the brass parts are oxidized, which is natural. Please purchase with understanding. As it is a limited edition, the distribution volume is small, and it will not be produced again. The 2020 blue version is also rising in price, so this one is likely to follow suit. Returns and exchanges are not accepted. The sale period is scheduled for one week, but it may change without notice. Please note that the listing may be stopped suddenly. Returns and exchanges are not accepted. Thank you. I will also include a small bonus. As shown in the fourth photo, it has been stored in a dark place with a light-shielding cloth. I think the condition is good, as it was stored in the same way as a Hi-Mech, as those who know will understand.
