We will be releasing a special 10th anniversary project, "Glass cullet Ring."

In 2025, HARIO Lampwork Factory celebrated its 10th anniversary.

As a special project to commemorate our 10th anniversary, we will be releasing a limited number of one-of-a-kind special rings made using glass cullet produced at HARIO's Koga factory.

cullet is glass fragments that are generated during the glass production process in factories.
In 2011, a large block of glass was created at HARIO's Koga factory in Koga City, Ibaraki Prefecture, due to a disaster.
At the time, with the desire to never forget this event, some of cullet from the lump were hand-processed into accessories. This was the catalyst for HARIO to start making glass accessories, and later became one of the reasons for the launch of HARIO Lampwork Factory brand.

To mark this milestone 10th anniversary, and to express our gratitude to all of you for the progress we have made so far, we have prepared special accessories made with these glass cullet.

Each cullet ring is a unique piece, each with its own individuality.
Each piece is handcrafted by a glass artisan using unique glass fragments of various sizes and shapes, which are the product of chance.The metal fittings are available in two colors: gold and silver.

We hope you find your favorite one and enjoy the natural sparkle of cullet in your hands.
