The second special collaboration between Japanese bag brand pionunnal and FEILER will go on sale on March 9, 2026 (Monday) at 12:00 PM. The collection, titled "PIOFUL," takes inspiration from FEILER's popular "Joyful" design — a pattern that lets parents and children explore the alphabet together — reimagined as a pionunnal original.
PIOFUL Design

PIOFUL is pionunnal's special take on FEILER's beloved "Joyful" pattern. Each letter in "PIONUNNAL" is paired with a playful motif:
- P – Popcorn

- U – Umbrella
- A – Angel
- L – Love Letter
