Bringing "I’ve always wanted something like this" to life together.
A smartphone case made just for you, born from the real voices of 100 people.

Maika collaboration top
What COVERARY values is not specs or trends but the comfort of each person who holds a smartphone every day.

This special project started from conversations with maika, a COVERARY user, and many users beyond her.

This is a new form of co-creation where the brand doesn’t create unilaterally but builds on what users say "this is good."

Users’ honest opinions became the blueprint

Users’ honest opinions became the blueprint
What came through SNS were many honest opinions noticed only because people use the product every day.

"I want to engrave on a cute case!" "I want a mature case in a pale color." We carefully listened to each of these voices and shaped them together with maika over about seven months.

This is not a design for a specific person but an update to support users’ daily lives. That’s why it will naturally fit into your life from the day you pick it up.

Balance reached after many prototypes.

The first sample looked cute but when the smartphone was attached, the scrunchie stretched due to the weight. That slight difference changed the impression of volume.

We calculated the size down to millimeters, considering the weight of the smartphone, to achieve a balance that looks "properly cute" both when held and when placed down.

The most common request on SNS was, "I want a pale color that’s not too sweet."

So, focusing on mature cute nuance colors, we tested compatibility with all colors of COVERARY’s classic Italian shrink leather. After many combination tests, we carefully selected only five colors that look beautiful with any leather color.

By "choosing," find your own perfect answer.

COVERARY’s greatest feature is the "customization" that users complete themselves. We provide the base design for this product, but you are the one who finishes it.

This special feature was born from requests by maika and users who wanted to match the hardware color with the engraving color.

Normally, only gold engraving is available, but for this collaboration, you can choose the engraving color from .
Heart-shaped pouch available for purchase as a set

A heart pouch with a strong presence that becomes the highlight of your outfit. Its practicality, allowing you to quickly store small items like lipstick or earphones, is also appealing.

This is a recommended additional item for those who want to go out light◎ Since it’s made from the same material as the case, using them together enhances unity and gives a sophisticated impression.

We do not mass-produce. After receiving an order from a user, a Japanese craftsman carefully makes each item just for that person.

This is COVERARY’s wish: "We want you to cherish your customized items for a long time."

We hope this case, filled with the thoughts of maika and other users, becomes a special presence that adds a little color to your everyday life.

Please find the combination that suits you best.
