Our Story
We go to Japan for our beads. Here's why.
Hello, we're Tom and Janine, the founders of Koss Design. Since 2020, we have built Koss Design - a jewellery brand with French roots - around one obsession: the finest glass beads in the world, made by MIYUKI in Japan.

A letter from us
How two people with a marketing career ended up threading beads.
After many years working in marketing, we decided to dedicate ourselves to what mattered most to us: creating unique jewellery that celebrates femininity and enhances every woman's natural elegance.
We named the brand after the Norwegian word Køs - those precious moments of comfort and harmony when everything feels perfectly in place. That is exactly how we want our jewellery to feel: light, joyful and easy to wear every single day.
Most of our pieces are designed in Paris, and all of them are crafted entirely by hand. We choose flat Japanese beads instead of traditional round ones, because their shape creates a modern, refined look you won't find anywhere else. And we produce in small batches, with exclusive colour combinations - so every collection stays special.
Today, more than 150,000 customers wear Koss Design, and our pieces are stocked by over 50 boutiques in France and internationally. We still read your messages every day, and we still get excited about every new colour.

Why MIYUKI
Not all glass beads are equal. We work exclusively with authentic, certified MIYUKI beads.
Japan's bead maker since 1935
Founded in Fukuyama, MIYUKI is Japan's oldest bead manufacturer still in operation.
Made in Japan
Every MIYUKI bead is produced in its own factory in Fukuyama, from raw glass to finish.
Perfectly uniform
Precision-cut beads of identical size - why our bracelets stack so beautifully and feel so light.
From Japan to your wrist
✨ Made in small batches - once a colour is gone, it's gone for the season.

"Received one set and bought two more"
I received a set as a gift and immediately went online and bought two more sets! The history of the glass beads and the simple design that amplifies their beautiful colors, render them treasures that you will delight in wearing.

"So light you barely feel them"
They are very uniform in size so are great to stack. When I first placed an order I was not sure exactly what to expect but was pleasantly surprised to find they are really nice. These are nicely made and are so light you barely feel them on your wrist.

Your questions, answered
Everything our customers ask before their first order.
Are these real MIYUKI beads?
Yes. We work exclusively with authentic, certified Japanese MIYUKI beads - far from the low-quality imitations often found online.
What if the size doesn't fit?
You have 30 days to request a size exchange. Just email us at support@kossdesign.com with the size you need - we reply within 24 hours.
What if a piece arrives damaged?
Every piece is quality-checked before it ships. If anything arrives damaged, simply send us a photo at support@kossdesign.com and we'll take care of it.
Where do orders ship from?
Every order ships from France with full tracking, and arrives in our signature satin pouch.
Are they hypoallergenic?
Yes. Authentic MIYUKI glass beads are naturally hypoallergenic and safe for sensitive skin.
Can I wear them in the shower?
MIYUKI glass beads are water-resistant, but we recommend removing your bracelets before showering, swimming or sleeping. This preserves the elastic and keeps your pieces looking new for much longer.
A final word from us
If you have read this far, maybe you are still hesitating - and we truly understand. Ordering jewellery online, from a brand you have only just discovered, takes a little trust.
So here is our promise. Behind Koss Design there is no faceless corporation - just the two of us and a small team who care about every single order. If something isn't right, we will make it right. If your size doesn't fit, we will exchange it. And if you simply have a question, write to us at support@kossdesign.com - a real person will answer you.
We started Koss Design because we believe courage is the magic that allows dreams to become reality. Whatever path you choose, always do something that brings you joy - life is precious.
Thank you, sincerely, for taking the time to read our story. We hope you will love wearing our jewellery as much as we loved creating it.
With love,
Tom & Janine
