Uni-ball One P × ob1toy – Limited Edition Gel Pens (2 patterns)

A charming collaboration between Japanese illustrator ob1toy, SANBY, and Uni-ball, these special edition Uni-ball One P gel pens celebrate the playful and nostalgic world of Japanese stationery.

Available in two exclusive designs — Retro Post and SHIPS CAT — each pen features original artwork by ob1toy and includes a removable acrylic charm inspired by its theme. The compact, rounded body is based on the popular Uni-ball One P, a pen loved for its comfortable grip and pocket-friendly size.

Beyond their collectible appeal, both pens deliver the excellent writing experience that made the Uni-ball One series a favorite among stationery enthusiasts. Their pigment-based black ink produces crisp, high-contrast lines, while the fine 0.38 mm tip offers precision for journaling, planners, note-taking, and everyday writing.
