Created as a commemorative gift for this event was
an amulet leather case by NO SIGN.

✔ Production Details

・Amulet leather case
・Corporate color (green) design
・Integrated production of paper bags and shop cards

This is an OEM project designed not as a mere product,
but as a brand experience.

■ Why Leather OEM is Chosen

While there are various options for novelties,
the reason "leather products" have been chosen in recent years is clear.

1. Long-lasting use (= Increased touchpoints)

Not disposable, but used daily.

In other words,
your brand continues to have contact points with the user.

2. Ensures a sense of luxury and reliability

Leather inherently conveys:

・Quality
・Durability
・Reliability

as a material.

3. Easy to imbue with a "story"

Just like in this project,

・Travel
・Prayer for safety
・Memories

by combining these contexts,
it can be elevated into a meaningful product.

■ Design Points of This Project

① Conceptualizing an "Amulet"

A trip isn't over until you return home.

Designed as an "amulet"
to wish for a safe return.

② Reflection of Corporate Colors

Adopted the green that symbolizes Solaseed Air.

・Leather
・Stitching
・Accessories

Everything is unified.

③ Experience Design Including Packaging

・Paper bag
・Shop card

These were also all custom-produced.

Why go to such lengths?

The answer is simple.

Because the experience of the moment you receive it becomes the value.

■ Points to Avoid Failure in OEM

Common challenges companies face when considering OEM:

・Looks cheap
・Does not fit the brand image
