2025AW Season
The standard size that becomes the centerpiece of your outfit
In the 25AW season, the standard size made a comeback with quilted and foil-finish designs.
Available in a wide range of colors—black, brown, silver, and gold—it makes the perfect accent to your outfit.
Note that the chain is not included, so you can enjoy customizing it with your preferred one.
PETIT size that can be used like an accessory
In the 25AW season, a new PETIT size was introduced.
Compact enough to attach to a belt loop, this playful item invites you to pack it with dreams or sweets and take it on a journey.
You can enjoy various styling arrangements by attaching it to your existing bags or cake bag.
As it doesn’t hold much, we recommend using it as an accessory.
A simple yet striking design
The Standard size features an expanded quilted surface, creating more sculptural shadows.
It is constructed without any stitching—formed solely by round metal studs.
These prominent round studs add a bold touch to the otherwise minimalist design.
The PETIT size, small enough to fit in your palm, adds a charming, feminine accent to your outfit.
A personalized design completed through customization
The magnetic handle produces a satisfying sound when opened and closed.
A large O-ring is attached to the side, allowing you to add chains or your favorite strap for a one-of-a-kind design.
At our store, pairing it with a KAMIYA wallet chain has been especially popular.
The surface also features a three-dimensional brand logo for added character.
Durability and Character Brought by Cowhide × Foil Processing
The material, as with the 2025SS season, is cowhide treated with a foil finish.
Thanks to the durability of genuine cowhide, it can be used for many years.
The foil on the quilted surface develops subtle abrasions with use, gradually maturing into a subdued shine over time.
2025SS Season
In the 2025SS season, the Cake Bag’s Mini size was updated.
With two variations—glossy cowhide embossed with a quilted pattern and metallic leather finished with foil processing—the bag gains greater visual depth and playfulness.
While retaining the structural beauty of seamless construction, round studs, and a magnetic handle, the three-dimensional pattern reflects light from multiple angles, enhancing its presence.
Available in three colors—black, brown, and silver—the bag offers versatility, making it easy to incorporate into everyday styling.
Chains are not included; instead, a studded belt was released separately.
The brand’s philosophy of “something that feels familiar yet looks new” was made even more vivid this season through the renewal of materials.
Gloss and Metallics as a Refined Accent
The round studs resonate with the grid-embossed quilting, creating complex shadows and bringing a natural expression to the surface.
Unnecessary details are eliminated, leaving only the brand logo and studs for a minimal design.
This restrained detailing preserves the beauty of the quilting, resulting in a harmonious appearance.
A Minimal Design Stripped of Excess
The round studs overlay the grid embossing, generating intricate shading that gives the bag a natural expression overall.
There are no unnecessary details—only the brand logo and studs form this minimalist design.
These minimalist elements allow the quilting to stand out, elevating the piece into a well-balanced item.
Two Faces of Leather: Gloss and Foil
Both the glossy cowhide and the foil-finished leather offer excellent durability, allowing you to enjoy their solid texture for years.
The foil on the quilted surface develops fine scuffs with use, gradually settling into a subtle, elegant luster over time.
2024AW Season
The Cake Bag first made its debut in the 2024AW season.
The initial release featured two sizes: Standard and Mini, in a black-based color scheme accented with white.
Designer Shinpei Goto stated, “I want scratches, stains, and even wrinkles to become memories,” advocating for a relationship where the owner and the bag share a story through the passage of time and the patina of use.
A Unique Design Inspired by Cake Boxes
Based on the square form of a cake box, the softly rounded corners create a distinctive impression.
The round studs serve both a functional role and an iconic decorative element, adding visual rhythm.
The Essence of Design in the Details
The handle is embedded with magnets, allowing smooth one-handed opening and closing.
The satisfying snap when the handle closes by magnetic force evokes the excitement of unwrapping a gift in everyday life.
A three-dimensional brand logo embellishes the front.
The included chain strap balances rugged texture with practicality, while chandelier-like parts add shimmering highlights reminiscent of “raindrops,” embodying harmony between contrasting elements.
A Structure That Maximizes the Charm of Leather
Crafted from glossy natural cowhide.
Using a single piece of lustrous cowhide, the structure is formed without stitching, relying solely on round studs to hold the three-dimensional shape, resulting in a minimal yet sculptural presence.
As you use it, the leather deepens in color and develops a richer patina, allowing you to enjoy its evolving beauty over time.

What is the Cake Bag? From Concept to Sizes and Styling
The core concept behind this bag is “to let people experience in daily life the happy feeling they get when carrying a cake box.”
By translating the excitement and anticipation that surrounds cakes—symbols of special moments like birthdays and anniversaries—into the form of a bag, it becomes something you can carry with you anytime.
Designer Shinpei Goto sees fashion as “something that enriches and brings joy to life,” and the Cake Bag is the item that most purely embodies this philosophy.
This universal concept was inspired by a scene Goto once witnessed.
On a rainy day, he saw a man—likely a father—walking while carefully holding a cake box to keep it dry, and he found deeper meaning in this ordinary gesture.
He described the protective, gentle action of trying to keep something precious safe as “like seeing a hero.”
This inspiration ties closely with the masculine image MASU continues to explore.
The Standard size can hold a wallet, smartphone, and a 500ml water bottle.
The Mini size is ideal for carrying just the essentials in a compact, everyday style.
The PETIT size fits small items like AirPods or lipstick and can be attached to belt loops or other bags like a charm.
Worn crossbody with a chain strap, it keeps your hands free—perfect for strolling around the city on weekends.
Carried clutch-style with the handle upright, it complements formal outfits and stands out at dinners or parties.
Its greatest charm lies in the way it ages: scratches and scuffs are embraced as memories, allowing it to evolve into a one-of-a-kind vintage piece over time.
