Rollbahn releases 2027 diary collection with new mini size

Delfonics has released its 2027 edition of Rollbahn diaries, which begin in October 2026. The product lineup features 691 variations, including two main lines: the playful ‘Rollbahn Diary’ and the classic ‘Delfonics Diary’.

A new ‘mini’ size (82 x 105 x 15 mm) has become a major point of interest due to its portability, as it is small enough to fit into clothing pockets. Despite its compact size, the mini diary maintains a functional layout including monthly schedules, year calendars, and 121 pages of grid memo paper with perforated edges for easy removal.

Demand for specific designs has led to intense competition among consumers. Limited edition designs sold at Loft, featuring motifs such as sweets, food, and the zodiac animal of the year (sheep), have reportedly caused a scramble among shoppers, with some items selling out quickly both online and in physical stores.
