oh lolly day [Pen] HAPPIER MART pen [mart black]

The HAPPIER MART pen is created through an official collaboration between KACO and oh lolly day, featuring the signature oh lolly day character design and a carefully chosen mart black that makes it a pleasure to hold and use. Whether for journaling, daily planning, or desk writing, this pen is designed to make the act of writing feel special every time.
