Opantsu-kun × REN
A Playful Collaboration Bringing a Little Humor to Everyday Life
Free despite wearing nothing but underwear. Or perhaps free because he wears nothing but underwear. REN is pleased to introduce a special collaboration with Opantsu-kun, a surreal yet lovable character.
Opantsu-kun is a popular character created by Kanako, a model and illustrator.
Kanako and REN have shared conversations over the years, including interviews featured on our website. This special collaboration grew naturally from that ongoing connection.
COLLABORATION ITEMS
For this collaboration, we have created special editions of our signature Kite Shoulder and Day Shopper bags, each featuring a dedicated pocket designed to fit the Opantsu-kun pouch perfectly.
With Opantsu-kun peeking out from the pocket, these bags bring a subtle touch of humor to everyday life—a playful way for adults to enjoy carrying their favorite plush companion.
