✨ Obon Special Event ✨
🇯🇵 Japan Jewelry Fair 🇯🇵

Hello everyone! 😊
This is MAI, the signboard girl of MPM Musashi. 🌷

We wanted to bring you some enjoyment during the Obon period, so we decided to hold this event!

📣 We've decided to host it!

And so...

💎 Japan Jewelry Fair 💎

will be held! 😊


🇯🇵 KOFU JEWELRY 💎✨
Japan's Pride to the World

Actually, JewelryDIANA is...

Manufactured at a jewelry factory in Kofu, Yamanashi Prefecture,
which supplies OEM to globally renowned brands ✨
It is produced with the craftsmanship of Japanese artisans,
cultivated over many years since the company's establishment.

These are Made in Japan jewelry pieces 😊
each carefully finished by Japanese artisans.

Furthermore, as we are a manufacturer-direct store,
we can offer prices that are truly achievable ✨

We strive to deliver high-quality jewelry,
which would normally be more expensive, at the most affordable prices possible 💎

That's why this fair is
such a great deal! ✨

🌈 From MAI

Lately, there have been so many things happening, and sometimes you just feel a little tired, don't you?

But,

"Only you can cheer yourself up."

With that in mind, we decided to hold this fair 😊

I hope you can find your favorite jewelry, feel a little excited, and smile even just a little bit! ✨
