Cinnamoroll turns into plush slippers: sleeping pose is a collectible must

ATTISESSION and Sanrio designed this collection around the theme “BEDTIME STORIES,” imagining the quiet, comfortable moments just before Cinnamoroll drifts off to sleep. The entire lineup uses soft tones reminiscent of a night sky, incorporating stars and plush materials to give the familiar, adorable character a romantic touch.

The absolute highlight of the collection is this pair of room slippers! Resting on the top is a sweet, fast-asleep Cinnamoroll with closed eyes. Paired with a dark gray base and shiny star studs, it looks just like the character cuddling a star to sleep. Compared to typical cartoon character slippers, this design offers a chicer palette and thoughtful details. Placed in your bedroom, it serves as an uplifting piece of decor. Just imagining slipping into these soft, adorable slippers after getting home from work is enough to win you over. Priced at ¥6,930, the slippers make a wonderful treat for yourself or a sweet gift for Cinnamoroll fans.

Don’t miss the star mini bag and adorable plush keychain: bring Cinnamoroll into your everyday look

The sweetness doesn’t end there! Anyone who loves bags and small accessories will fall for the collection’s star chain bag. Featuring a puffy silhouette studded with stars, the white body and metal chain give this mini bag a cool, sweet edge that pairs effortlessly with fall and winter knits, leather jackets, or denim outfits. The chain is detachable, letting you wear it as a crossbody mini bag when heading out or use it as a pouch for daily touch-ups. It retails for ¥6,930.

Another item to add to your wishlist is the Cinnamoroll plush keychain! Along with its fluffy shape, it features night-sky stars and a coffee cup charm printed with the ATTISESSION collab logo. Clip it onto your daily bag for an instant touch of playfulness. Priced at ¥3,300, it’s also the most accessible piece in the lineup.

Even the T-shirt hides clever design details: Japan-exclusive collab now open for pre-order

Alongside the cute accessories, ATTISESSION brought in classic American apparel brand Healthknit to create a three-way collaborative two-pack T-shirt set. The two tees feature a specially crafted Cinnamoroll jacquard knit fabric and a subtle glitter print design, respectively. Wear them on their own or layer them under fall cardigans and blazers to let the cute graphics blend naturally into your everyday style. The two-pack set retails for ¥14,960.

The Cinnamoroll × ATTISESSION collaboration will officially launch on November 14, 2026, at ATTISESSION stores in Shinjuku and Osaka, Japan. Pre-orders are open on the official UNITED ARROWS web store from November 2 through November 11, with the official online release following on November 16. From sleeping Cinnamoroll slippers to night-sky star bags, every item hides details that bring a smile to your face.
